Rust actually supports M68K so the real problem is if you could buy new Alpha chips. I don't think you've been able to do that for a long time.

As I understood it (I never used them) the M68K chips had a sane design, unlike the x86 ones. Maybe the reason you can still buy them is people value them for their simplicity and "easy to understand"ness - that can be worth a lot.

The current m68k chips (ColdFire) are a reduced and simplified version of the original instruction set. I doubt that a backwards compatible 680x0 with the addition of SIMD, 64-bit support, CFI, virtualization and whatnot (for example system-wide innovation such as multiprocessor and a fast superscalar microarchitecture) would be overall any more manageable than x86.
