I imagine the leviathans would fit on your fuse.
M8 is required.
At my size I know from firsthand experience that would it not be stiff or stout enough front wing connection. You may be fine at 75kg.
If you can uphaul and slog around on the Wizard 114 I reckon it would work fine. The foils are easy to turn and handle but you need enough float and stability to handle really light lulls with chop.
You may not need as much foil as I am using.
Your right it would be good to have an app that could help wade through all the options.
At the moment I am enjoying the challenge of exploring a design space that doesn't come with instructions.

I was thinking about Leviathan 1150 or Leviathan Pro 1260 + M6/M8 washers.

Also saw PTM999 and PTM1001 (are there even bigger HA Slingshot foils ?). Anyone experience with these foils for low wind in addition to PTM926.

I heard some brands (like Duotone) stop warranty with spans bigger than 100 cm.

So better not go to wide as well for turning.

Would the stress on the long carbon mast W103 be to stong ? I could use my old Hover Glide 90 cm with connector piece.

Slogging and uphailing sail on Wizard 114 liter is no problem for me at 75 kg, but I notice and friends say the rear of my board is low in the water creating drag.

PTM1001 is worth trying, it's faster with a lot more glide than the 926

Here is one not that silly setup for light winds. A big but not too slow front wing (SAB W1100, 2100 cm2 in this clip), and a light weight freestyle rig. A rig that is not too big + a big foil combo allows all kind of fancy pumping, like that "rowing through the air" type of pumping at 00:45, and that one in the very beginning at 00:05. Neither of these are easy (or even possible?) with big and bulky sails I think.

It is the connection at the front wing that is weakest link with the compatible Sab and Slingshot options. Your mast will be fine.
I would strongly advise against using M6 bolts, you want to drill and tap or drill and add inserts to your fuse so you can use M8 screws.
I would recommend that upgrade even if you don't go for a bigger wing. Take it into a metal shop and have them do it if you not interested in DYI. The bigger screws are more forgiving and tolerant of sand and cross threading not to mention a lot stronger.
I have no experience with the Leviathan or PTM but the Leviathan are higher aspect.

Does this mean drilling through the fuselage and then treading, or can it be treaded without drilling through the fuselage. I have a threading set but this gear is for threading an open hole.

Once upgraded to M8 how do you fix the old PTM or PFI foils of Slingshot. Is it needed to make a tapered wider hole in the Slingshot frontfoils ?

The fact that you have taps and understand they are for open holes means you absolutely can do this.
The time for a machinist to do it is less than an hour so less than a new fuse. Either way it is a good thing to do and many of us on this forum have made this mod.

These are commonly available tools, but they are specific types of taps. Drill with the supplied bit, or be very certain you have the exact diameter bit required. Measure the depth of the hole and mark that depth on the bit with tape as a guide. Start threading with a "starting" tap. It has a taper on the tip with several lead-in threads. Like the name implies, it's designed to make starting easy and straight. It is likely that a starting tap is what you already own. Then use a "bottoming" tap. Its tip is much less tapered, and the threads go almost all the way to the end. This tap will cut threads nearly to the bottom of the hole.

Helicoil inserts are another route you can look into. They come with good instructions and often installation videos. Same steps really. I have struggled with the inserts. There is a length of the wire that is used to hold and install the insert that is designed to be hammered out and I sometimes can't get that out. Usually, I can get full thread engagement and just leave it.

The wings are easy. Drill with a normal M8 clearance bit. Then enlarge the tapered hole with a 90-degree countersink. Go slow and keep testing with the fastener until it sits flush with the wing.

If you botch tapping, you can still use inserts because there o.d. is bigger, the inserts can be replaced. If you botch the inserts a machine shop can still bail you out.

I know this stuff from experience; I broke, bent, cross threaded and stripped a bunch of M6 wing bolts before the industry acknowledged that M6 is too small.

I think for a lightweight rider using wings under 1m and not jumping a quality M6 is fine. I'm far from light and never had an issue.
I'd definitely do helicoils or possibly Chicago nuts if going M8
