It looks a bit lonely here with no responses to your question. I have no experience with mixing and match the rig components but for the sake of solving a problem I would break it down into two questions. The first would be finding out if the sail and mast could be rigged on land, so if you have the items it would be easy to try and see. If it looks ok on the land then the next thing would be to test it on water. Therefore, the second question would be about performance and ease of handling - all personal preferences so you are best to judge.
In a perfect world, all windsurfing gear would receive huge government subsidies, making everything dirt cheap. Then you could buy whatever you wanted, within reason. Better wait for the inheritance instead 
Hi Adam I have tried a naish in my simmer race sails and it ok ,as my Naish mast is resent ,depending what year the mast is old once where hard top ,Naish has gone to constant curve now
,a north or duotone would be better ..Pryde might be ok too .
Hi,
I have attached the unifier mast selector. Says they are both constant curves and after looking at the simmer masts online I'd say it wouldn't be far off.
