Indeed, life has a knack for interrupting the fun things we'd like to do.

Perhaps when it warms up this Spring, you can continue...

As a previous owner of GMA speakers I would suggest you finish your cosmetic work and then spend some time listening before messing with the crossovers.  While yes to a point Roy had to parts source to a price point he also parts sourced to a voicing he thought was correct for his designs.  Following the advice of Kenjit and others and making wholesale changes and upgrades may result in nothing more than an unlistenable speaker with premium parts.  I would trust Roy's judgement over the "self appointed" experts. But feel free to trust whoever you choose.

i won’t do anything beyond the veneering and surrounds until I listen for a bit. I will look things over on the cover to make sure no leaking caps but otherwise no immediate changes.  I have a decent number of high end caps in my tool box so at some point I might tinker but I would make sure the existing unites were mapped and saved for reinsertion. 

What I would love to do but won’t, is cut the top 4 inches of the speaker off, the obelisk, and make it flat. Veneering those is an absolute bear. I had every finger bandaged from razor cuts on the first one. The reason I didn’t start the second was I am rethinking the process to possibly find an easier but aesthetically attractive approach. 

And if anyone else is considering veneering over cultured marble with a variety of angles……… I wouldn’t recommend it. I have found a successful process, but it is a pain. I intentionally have let them set for a few months to see if the adherence is stable. Even the speaker cut-outs have no wiggle room so after veneering them I had to slightly turn down the holding rings by 1/32”
