Sounds a lot like a good strategy. I like it, but can you create the image in less time, so then you don't have to act like a nit for an hour or so? Also try to watch the regs and pick their tendencies and their weak plays e.g. checking behind instead of c-betting with the nuts.
If I were to play 5NL, I would play some ABC with a mix up here and there. Against regs, I would tend to play small ball and even calling with a gutshot on the flop hoping to catch on the turn for implied odds
. I bet my AK, AQ hard when I hit that ace. Because I know that many people will call me off with even A2 offsuit.
