I have two STFs with 4 MiB RAM available and will do the test later. (I
also have an STE with 4 MiB, but from your message I guess you're not
interested in that.)

Notice that there are two different MMUs in STFs: the one made by IMP
and the one not made by IMP. They behave differently when the sizes of
bank 0 and bank 1 don't match. Luckily I have both at my disposal. Which
one do you want tested?

Also, I'm not sure if I posted it here already, but this is some insight
on how the MMU maps CPU addresses to RAM address lines:
