I think it will be fine, will you run co2 to grow the HC carpet? Co2 with shrimp is like a game of roulette. I accidentally overdosed of Excel once, and all shrimp died.
That sounds like a good stock, just do some frequent water changes when you add those 10 cardinals, to offset any rising ammonia level, since you won't have the plants to counteract it, just in case.
