Speak to Titleist or your fitter. Bending irons will affect the bounce and possibly playability, but it can be done.

if you custom fit it it is always possible to make you're clubs 2 degrees stronger, but why are you choosing to get the t350's instead of the t200's?

Hitting my T300 irons, it was clear the 6 iron didn’t gap well over the 7 iron. Fitting the T200 7-48’ and a T 350, the 350 gapped with the T200 without playing the degree loft game. It’s all about the distance, not the loft.
Especially with the 3rd Gen T series irons offered as a full package solution, the goal is to find the best iron, and if your ability drops off going to the next iron, then they have a tool to move to. Everyone one I’ve talked to has guessed wrong on what their set would look like. I wouldn’t worry about a distance gap until your skill set required a different iron. I never thought I would be fit in the T200. At roughly $200 per iron, why guess when you can get a $100 fitting from a Titleist sponsored fitter with lots of training and experience with the T series irons to maximize your potential.
The pros adjust their lofts for window and distance. Keeping exact loft degrees spreads is not how they fit irons.

This is a great discussion for you and your fitter to go over. One of the main objectives of a thorough fitting is to ensure your clubs are properly gapped from top to bottom. If a blended set is right for you, then the correct clubs/lofts will be worked out during the process.

The T150s are forged, it shouldn’t be a problem bending them 2 degrees stronger. But they’re already strong lofted compared to traditional irons.
