PL Omaha Hand Small Pot

[tortoise]

Im used to winning small pots with monsters in Pl, but this hand was different due to the number of callers. Was there a way for me to win more? I have no reads and all stack sizes are fairly even.

I have AA-68o on button. 5 limpers to me I raise to $2, 7 see the flop.

Ah-A-3h

Player to my right bets $3, I will wait to the turn to raise but 4 call!!!!! Turn a blank (what isn't?)

Player bets $4. I don't want to lose 4 callers, I put better on 3-3 and can't bet too much to lose him either so I just call. 2 call. River blank.

Bettor steps out with $4, I raise to $15, all fold, he calls and I take down a pot that seems too small considering the strange action.

I've never seen so many callers before with a flop like that. Was there a way for me to make more? I was thinking maybe a small raise on the flop? Or is that just hindsight?
