Putter Adjustment Help Needed

[wakefield724]

I use an Odyssey stroke lab Toe Up putter. I love this putter and have been using it for maybe 2 seasons now. 
I tend to stand more over the ball when I putt and unfortunately the standard lie angle makes the heel elevated if I do so.

I took it to Dick’s to get a Superstroke grip on it so the swing weight would be more adjustable and I wanted to get it bent 2 degrees upright so it’s flat when I putt. 
 

The employee told me the hosel was too thin and it would snap. Was he right or should I take it elsewhere? If he was correct, would it be beneficial to replace it with another center shaft putter than can be adjusted?

Never bent this model but I don't see any reason it can't be done by someone who knows what they're doing (aka not Dicks in general).

It's also not a hosel, it's a stem mount if that tells you anything about the info you were given.

I used to have a similar shaft. I adjusted mine on a tree next to the 8th green.

A professional golf shop should be able to bend the shaft, not the hosel.
