I think by “fraculate” you don’t mean to make the rig fractional, but rather the technique of raking the mast forward, especially on a downwind run, to help with trim, correct?
If so, That sounds like a dangerous proposition on a mast head rig or any rig that’s not designed for it. You need to either move the keel step back or somehow bring the point where it leaves the deck forward. As you say, removing the mast wedges can do that, but then the mast will be unprotected against the deck, and will probably kink or dent there unless you soften the edge somehow. Also you’ll need to figure out how to prevent the mast from inverting with all of the rigging geometry changed. Boats like the Star class are built for this with adjustable mast steps and the deck rigging necessary to accommodate it, but on boats that aren’t I could imagine it going very badly.
