Oh yeah, lots of powerlifters use a very wide grip to shorten the range of motion, etc. and they can lift more that way.
I wouldn't recommend that to anyone though. Puts your wrists at risk due to the angle. For me, it does a funky thing in my shoulders too.
You gotta find what works for you for sure, but I would start out as safe as possible, then experiment afterward.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
