Understood, but I'm going to start looking in the way Rusty and Arnd
suggested with the vmalloc approach. This would allow for saving of
memory and dynamic allocation of module memory making it more robust. And
all this without that evil extra indirection!

Remember that this approach could effectively just move the indirection to
the TLB / page tables (well, I say "moves" because large kernel mappings
are effectively free compared with 4K mappings).

So be careful about coding up a large amount of work before unleashing it:
I doubt you'll be able to find a solution that doesn't involve tradeoffs
somewhere (but wohoo if you can).
