Pascal, Norm and Davis plus 2 first round picks is a pretty good haul for Houston which I think might get it done if Philly isn't trading Simmons. Raptors can withstand the loss of Davis and Norm since you have Lowry, FVV, Flynn Thomas and Harden in the guard spots.
You would be super weak in the front court but I'd trust the FO to be able to fill those spots.
