I'm thinking a trebuchet would be significantly more effective with some combination of improved pivots, standardized lead ammo, and reliable&repeatable shot release. A good understanding of ballistics wouldn't hurt either.

More range and accuracy.

Some sort of power take-off could be run along fortifications to power-reload crossbows.
