How far can you bend TS3.5 heads for loft?

I just built a TS3.5 five iron with a Maltby MPF Pro Series+ shaft. During the very first test drive on the range today I was impressed.

In looking at the lofts for the 9, PW, and AW, I would like to bend the heads -1, +2, and +3 respectfully. These changes get the heads closer to current set but still stronger.

I built a TS3 five iron with a Fujikura Vista Pro shaft and discovered I was loosing about 2 ½ yards of carry distance.

Can this be done without snapping off the hotel?

I bent a GW stronger 2 degrees so that i could get rid of my PW, and it increased offset too much, and looks hideous. Then i hated it so much
