Have a 16' x 32' Gambrel roof outbuilding with a loft. 2 x 4 rafters, , 24" oc. Attached to 2x6 joists, 24" oc. No center beam at ridge. It is 83" from loft floor to peak. Collar beams are 64" from floor. Can I remove some collar beams or move them up a few inches to get more head room. I'm 5'7 and would love to stand up in the loft. Any advice welcome. Picture of loft.

This is in no way to be considered structural advice.

But you could look at using a pyramid of plywood on both sides of the rafters. That would be a triangle of ply on both sides. So two pieces of plywood cut and nailed or bolted or over screwed.

He used osb. I would use ply.

You'll check the load bearing etc.
