that would work, only if the wording in the Bible didn't contradict it.
the Hebrew word for day, with no possibility of extra time (i forget the actual word), is used to describe the time. If God was being truthful to Moses when he was explaining it (he was, he's God), he would have said i made the world in 6 earthly days. But he didn't, he said "day" as in 24 hours, meaning that genesis is supposed to mean 7 literal days.
The Bible also makes it quite clear that God spoke the word and then it was so. It doesn't say he set forth a process that inevitably created the world as we know it. The Bible goes in detail about how man was made, and it doesn't involve evolving from an ape. Also, genesis is not written as an allegory. It means what it says.
I would not think that God would create the world via a process that is entirely random in its mutations and therefore in it's outcome. The evolution theory as a whole falls into the cosmic accident scenario for life on earth. Speciation falls into the creationist theory, but the rest of the evolutionary theory does not for ultimate origins (meaning we all came from amoebas does not fall into creationism).
It is a dangerous business, that of trying to reconciliate two opposing theories. Both have different world views attached. Trying to reconciliate creation and evolution is impossible, because adapting the Bible to what evolutionist say is saying that the Bible is not to be taken literally (then the life/death/resurrection of Christ is put into question, the very foundation of the christian belief), and inversely to have an evolution theory with a God attached is not the realm of science pure, and the evolution theory claims to be nothing but; to attach a God to a godless theory is nonsense.
It's a good theory, quite many people nowadays believe it. But those who do either then cannot trust the validity of the Bible and therefore the foundation of their faith, or they decided to believe in the unscientifically proven and the very bane of the evolution theory, God. (although, with the evolution theory, it wouldn't be the first time

sorry, i had to)
