It sounds possible. Is it because the cartridges physically won't
fit, or because the dampening rates are different. If its because of
different dampening rates, you may be able to install the cartridges
and move up to a stiffer spring.

Probably not. Most OEM dampers are designed with bump-stops to keep
the dampers from bottoming out.
And of you installed sport springs, they'd be LESS likely to bottom
out, not more.
Keep in mind though, that springs and dampers should be matched to
each other. A stiffer spring requires more damping -- one reason why
lots of after market suspension setup ride so badly. they move to a
shorter spring to lower the car, often by removing coils from the
factory spring. This increases the spring rate beyond what the car's
dampers are designed for and the car bounces around like a Model
T. Keep the dampers and springs matched and you end up with a nice ride.
