$200 NLHE Full Ring: AA trying to rep a bluff

½ live cash game, private table with all regulars.
Villain is a rather loose aggressive player. He plays strong post and preflop, and is capable of running some tricky bluffs. I generally try to stay out of hands with him, but with the hand I had folding pre was never an option.
Hero is big stack at the table, has been running well, and stacked at around $750 Villain is 2nd biggest. In this spot I decided I was going to try to represent a buff with my aces, unless something crazy happened on the flop. (Quads, or a really horrible board like 9-T-J diamonds.)
Most people around the table are Lag type players, so we have a lot of 3,4, and the occasional 5 betting light pre. I decided to four bet because I feel like the standard play is to just call when you are this strong, and the table dynm. Made it seem like I was probably doing this pretty light as a bluff. If he jams to try to pick off a bluff, I have the goods and will get super value from my aces. (He could fold, which would suck, but no risk= no reward)

I am never really afraid of a lone jack here. AJs and AJo jam pre to pick of a light 4 bet, JKo and JQs would probably have to honor a 4-bet, but if they didn’t I think he folds on the flop. J2 and J5 are really not really possibilities, and I don’t think he can flat this pre with J9. (He is way behind to a normal four bet, and still behind the upper side of my light range. He either 5 bets or folds this.) JJ is a possibility. He could have quads. I think if we fold because we are afraid of quads, we just need to quit poker altogether. 99 isn’t out, and he could play a set this way, but there are only six 99 combos out of a ton of other hands he could have. Again, I think folding for this reason is just searching for monsters under the bed. 55? I think this goes out the window pre. All that leaves us with is over pairs and maybe TT. TT+ could probably flat pre and expect to be ahead most of the time.
So, here is the question. Did I rep the bluff well? Would this work and get value against AK or a low pocket pair? Is this play worth trying again, or did I just get lucky here with him having an over pair? Will it get value against 2 or 3 other players?
Thanks in advance!

I think you might be over analyzing this one.
I think you got lucky with villain holding QQ.

He most likely didn't have you on AA or KK, and tried to use the river to represent holding AJ, KJ or QJ.

I have no issues with changing up how you might play any starting hand. Just realize what you are doing and don't get married to it if you played it wrong.

Looks like the result was great in this case.

The problem with "representing a bluff" is that its very unlikely you play that many bluffs this way. If this was a competant player he would have folded. I also dont like the idea of assuming AJ and isnt in his range. Assuming he 4bets them pre is giving him a lot more credit then you should give even lose aggressive players. Even if hes capable of 4betting it, its better to think along the lines of "he might have 4bet AJ, but its still possible that he flatted AJ pre" ... generally, i would say you have to have specifically seen him 4bet AJ pre before you can assume hes even capable of it. And even then, 4bet ranges are so situational, he might be flatting a wider range just because he has position
