Certainly possible, and would address the whole function pointer thing,
although I do question the performance hit because of the extra jump,
especially for small procedures, as well as the fact that the function
overhead would still be present. Certainly a safe start though.

I figured that virtual methods would be no-go and that this would

completely though because there's a huge number of procedures that
compile to the same code, especially when generics come into play,
and I have identified a fair number in the compiler itself (at least
when compiled under x86_64-win64).
Instead of complete elimination of the duplicate function code you can
replace it by the unconditional jump to the single copy of the
function code.
