Another idea: BAC Tankmaster. I have a BAC Jet Provost in my stash. Not sure why I bought it since I usually focus on WW2 subjects. Probably because it was inexpensive and the parts could be good wif-fodder.
Anyway, how about BAC creates a bargain basement specialized tank killer conversion of the Strikemaster by removing the right seat to make room for a big anti-tank gun, along with underwing stores? I'm thinking replace the Jet Provost's wide canopy with an assymetric single canopy and create gun space in the former right seat location. Maybe even a pair of 30mm DEFA or ADEN, or maybe something bigger, along with a pair of underwing anti-tank missiles?
Just musing at this point, but it could be fun.
