Can the MVCC implementation be swapped via Postgres extensions?

No. It would be a major surgery on the internals. See the article for my comment at the attempt to do this with the Zheap project:

Shame that zheap seems to have fizzled out. Do you think there's any prospect of it being resurrected and eventually mainlined?
