Longer Newtonian Collimation Bolts - Has Anyone Tried Them?

Hello Everyone,

It's been a long time since I've been on here, and what better way to make a return than to ask a silly question

Has anyone taken the path of using longer bolts to move the primary mirror of a Newtonian further up the tube? My reason for this is to achieve focus with a dslr. I know I can cut the tube but would like to try a less destructive approach first

I have the standard blue Skywatcher 8" f/5.
