Now, by virtue of rotation speed being a function of stall speed, I
conjecture you'd have to liftoff at a faster airspeed which would
equate to a longer takeoff roll.

Since your stall speed is invariably higher, you'll eat up more runway
when landing.

In both cases, it's not just the higher speeds involved, but the increased weight
also means that acceleration for takeoff and deceleration on landing will be
lower. F=ma with a (more or less) constant F, and increased m means
decreased a.
