The default 4E setting has a number of deities. Some people like them; some don’t. But just because you don’t like them doesn’t mean you need to throw them out with the bathwater.
The easiest way to make the gods feel different is to simply rename them. Corellon might strike you as some wussy poofter god of pointy-eared tree-huggers; call him Apollo, and he might seem just a bit less wussy. Ioun could remind you too much of floating rocks that orbit your head; turned into Odin the Rune-Finder, he regains a certain gravitas and respect.
Purely as a side-effect, this also makes it dead easy to add more colour and flavour to the gods. Need to spice up Tharizdun a bit? Make him the god that bit off Bahamut’s hand. Stealing that from the myth of Fenrir and Tyr took no work at all. The Raven Queen is pretty excellent as she is, but not too good to steal a few tricks from Anubis.
The following chart takes more than a few liberties with mythology, but it should serve for gaming purposes.
