How about converting the V-22 into a flying tank?
That is an actual program, but they’re scaling that back. One problem is that while it can be made into somewhat of a gunship, there are some major issues with the MV-22 in that role. Starting with the biiig nacelles on each side of the craft in vertical lift mode causing blind spots.
We’d be better off making our own Hind counterpart - and we probably should have. Those things are fearsome.
