Yes, one can "raise" the trusses (with the roof) but must correspondingly increasing the height of the walls supporting them .... which requires carefully designed bracing.

But as a architect you know it can be done too. adding weight to a roof requires apt walls. If you have 6x2 walls at 32" on center you can support some wood and tin. You can add, with no issues thousand of pounds of drywall and insulation and no one questions. Adapting 2x4 trusses with stick 2x6 scissor trusses are not bad or end all. Same metal hardware is available.
