Stop n go big stack vs very big stack?

[Shorty35]

Given the result, I definitely played this suboptimally but I would appreciate critique of my thinking about this use of a stop n go. We are near bubble (63 left 50 paid); I am above average stack, Villan is big stack. I only play to make final tables, so I am willing to gamble at the appropriate times. Villan has been very tight and appears to be solid player. I have shown down solid hands and also have a reasonably tight image. Here is the hand - my thinking follows

Preflop I was very close to folding -- didnt want to tangle with the big stack. But given how close we were to the bubble, I figured there was a good chance that he was using his image to steal. I also figured that this was a good chance to become a very big stack if I hit a winner.

I called with the intention of folding if I missed the flop or pushing if it hit. I figured that he might even lay down a big hand this way figuring me for trips or another very big hand. The flush draw was too tempting - and I pushed into his KK (he called instantly).

Apart from my flawed application in this hand, do you think there is any merit to the use of a stop n go as a big stack versus very big stack strategy. Or is there just too much gamble in that? Perhaps later in the tourney is a better time for this type of play?
