Good spot for stack-a-donk?

Villain is unknown.
No need for lenghty respones, just want to know if this is good/standard.

I probly raise to 7 pf, but i think i like betting 18 on the turn, pushing allows him to play perfect. With out a read that hes a donk i dont like it. This is a good move if you know he'll stack off with KK,QQ,KJ here.
