If you change a design to different wing sweep, don't forget
that it will move the center of lift in the direction of
sweep and it may significantly alter W & B and permissible CG
range position.

That depends on whether you sweep the tips forward or the roots
backwards.(Grin)

If the purpose is to move the wing spar carry-through structure aft of the
cockpit, the forward sweep is likely to leave the center of lift right where
it would be with the spar going through the cockpit with a straight wing.
