Elbrus are VLIW/EPIC, based on home-grown architecture.

The SPARC-based one is the old MCST R1000.

>who would be willing to fab it

Before the conflict, they used TSMC. Now, AFAIK, the only fab available is Mikron, located in Zelenograd near Moscow. And only 90nm process. There were some rumors about switching to SMIC, but I have not heard any updates for quite some time.
