No, it's not. Multiple calls to a PRNG generate correlated numbers, which can be used for an attack.
You need to use a PRNG that in a single call gives enough bits. And if you don't know that about PRNGs, you're not the one to be fixing this.
I talked about it in terms of entropy because that's the easiest way to see that you're not gaining anything except the illusion of gain, which will bite back some day. You can't get 112 bits of entropy by calling a 56-bit PRNG twice.
It's not progress if it breaks it.
