can it be done? Yes
Is it worth it? Probably cheaper to get custom domes cut for your application.
You need to dial in the existing dome to a gnats ass on axial and radial run out, and cut the squish. Most custom domes are cut on a CNC or prototrak lathe.
much easier than dialing in existing used parts.
Call and ask.
I am a machinist by trade, I'd buy new ones.
