No way does the 50/1.4 - or any prime - function as a kit lens replacement. You've got a few options if you really want to do everything the kit lens can do, but do it better (or do more as well):
1) replace kit lens with another zoom that is faster, sharper, longer, or otherwise does what you wish the kit lens did better
2) keep kit lens, add a prime like the 50
3) replace kit lens with a series of primes
Of these, I'd personally pick #2 as the cheapest / most effective way of giving th tools needed to improve your photography.
