I'm planning a new construction and had intentions of using an 8" R-32 SIP above a timber truss.  Does anyone have a recommendation on how to get an R-49 above a simple truss system.  I don't want an attic space.  Is it feasible to go to a 12" SIP and get R-48?

Sure. Some(most?) SIP manufacturers can also make custom sizes. Especially for a situation that is non-structural.
