The problem would be getting a veneer that's big enough. The EX style is a lot longer and wider overall than a normal guitar body (LP/Strat /Tele), so the normal veneer pieces from luthier suppliers will normally be far too small. The bigger the piece of veneer, the more it costs.

Though I have found this thin self-adhesive veneer, which is relatively low cost and comes in a sheet big enough (200cm x 60cm) to do a front and rear. You'd end up with a join line at the edges, but that would be far less noticeable than the current mismatch of woodblocks on the front of the guitar. https://www.thewoodveneerhub.co.uk/c...ck-wood-veneer

Whilst Sapelle is probably the closest wood to mahogany, this would probably better for getting that yellowish Korina look (though you'd have a mismatch between the top/back and the edges/neck.
