Any way to get the Story States effect from Custom/Budgeted starts combined with a scripted start's character context?

I know Custom and Budgeted starts have a Story States tab where you can flag plots like HQ and Project Genesis as already resolved, and the game builds your start around that. What I actually want is that effect, but layered onto one of the scripted starts (Terran Cadet, Abandoned, hell even Young Gun) instead of a blank custom slate. I want the starting context those give you, just without HQ and Pioneers hanging over the save from hour one.

Has anyone found a way to get Story States-style pre-completion on a scripted start? I've avoided mods so far, but I'm at a point where I'm willing to consider it.
