You could scale down the t-stud concept and produce a similar beam that was, say, 2" high instead of 6". In a skoolie, though, the only place you could really use it would be as "joists" for a floor, since the wall and ceiling insulation is already mostly into the cavities between the ribs. And you'd end up with about the same R-value as XPS foam board, which has sufficient PSI resistance that you wouldn't need the joists to begin with.
