I've done the same with some of my projects. I write enough to see what my mistakes are with my code, then dump it and start again. It's by no means perfect, but that initial "oops" phase can strongly help any software project by ironing out the potental bumps in programming.
Now, if you backing against a deadline and in this situation, it's a bit hard to do that, but I would at least try to find the ones that need dire rewriting and do that, such that other programmers at least see where you are headed.
