Double Cutaway FULLY hollows?

[Fourth Feline]

Hm, found another possible solution, fernandes sustainer?! Doesnt that give you endless feedback at low volumes too?! :D

Just an additional thought, if your main need for a fully hollow guitar is only for endless sustain at any volume ( implied more tangibly by your reference to the  'Sustainer' ) - a good old fashioned , hand held ' E-Bow' ( as used a lot by Bill Nelson in the 70's and still available ) - might meet your needs at minimum expense and no guitar surgery needed :

Howabout one of these?

Yeah, tried one exactly like that at the shop yesterday, i thought it was great, but i heard some problems with the cheaper parts, sure, one could mod but still, and im not sure i need the bigsby, but anyhow, that is a candidate. Preferrably id go second hand actually.

Check out some vintage Fender Coronados. fully hollow and kinda offset.

Just googled those. Never seen them before, i know there was the Starcaster (now used by that guy from The Killers), but i never knew of this ones existance.

It's mostly the electronics that leave a little to be desired. Still better than what you get in an Epi. If you don't need the Bigsby, don't use it. It's not like it's bad for the tone. It'll be hard to find one of those second hand, they're on the market since 2008.

If you go out to shop for one, check if all the electrics work properly, if so it will have little problems later on if you take good care of it and check the nut, these guitars are in high demand, some of the nuts are not as well done as I like to see them.
