You can but need a few very good crew and a bit of extra rigging.
You need two tacklines one that runs through the spinnaker pole at a time and a spare.
When you gybe you can take the weight off the pole with the spare tackline, ease the old tackline, take the pole off the mast, gybe the boat, push the pole back out easing one tackline so the one through the pole tackes the slack back up.
You also need a two braces and two sheets!!
WAY too much stuff for an E7.
