This sounds very much like the "complex relocations" feature supported
by some architectures (eg MEP, RL78).

I would say probably not. Obviously support for high level languages
is already working with ELF as it is. So if it isn't broken - don't
fix it.
This is not to say that exploring the idea is not worthwhile. It
might produce some interesting results. But I would be hesitant about
applying it to a generic tool like the linker without a real need.
Cheers
Nick
