It'll work, but remember that CP are long and skinny, making them easy to slurp down by the LMB. You'll need lots of cover for the CP to hide and reproduce in if you want to keep a viable population in the pond. Next problem is trying to source enough of them to get them established.
You might want to think about adding Golden Shiners (GHS) to the forage base too. Easier for the CP to eat.
