You seem to be saying a raise here indicates villain definitely has a king. I don't think that's the case at all. Many players will raise any pocket pair here to test the preflop raiser (as the raiser will have a tough decision with QQ-99 and will probably throw away AQ/AJ, and any sort of mixing-it-up-by-raising nonpremium hand). Limp/calling in EP could also easily be AK so I'm not sure why you're ruling that out. OP's plan to push if he gets raised is good in that most pairs below kings will fold when, by the FTOP, they should call and flip coins.

The move is not terrible against an unknown, but I'd prefer to do it against a player I already know to be capable of folding. Some players will correctly read OP's line as a big flush draw and will call with any pair and any king. Just because you don't know him doesn't mean he hasn't datamined some stats on you.
