I know. Not a good idea, but the building it's attached to is coming
down. Am I wasting my time, or should I have a go at moving it? I assume
that cutting it back might help, but any other hints, or should I just
buy a new one? I can't delay past this weekend, unfortunately.

Try it - nothing to lose - it's got to be moved anyway or you wouldn't
be doing it.

As Emrys & Hussein say, trim it back to manageable proportions first &
when you dig it up, take as much root ball as you possibly can.
Monana's have a wiry sort of root system that doesn't much like being
messed with (unlike hybrids with a bootlace affair that you can prune
back). Have its new home ready with lots of nice stuff to plant it with
& make sure you water it well. Even if it rains a lot, water it anyway.

It might die - it might sulk - it might be OK. But even if it protests
in the ultimate manner, at least you know a new plant won't take forever
to get to the same size.
