Hmm I do like the idea of an attack aircraft converted from K-8.
It looks like a good low speed, rugged plane which can be strengthened to carry a payload greater than its current 1000 kg. If modernized and loaded with some of the smaller munitions we've been shown (mini LS-6, FT-5, HJ-10) then it could make a very potent CAS platform while being relatively cheap.
Sort of like a mini A-10.
