Good luck mate. May Celestia grant you her blessings.
Now that you mention it, there are a few indistinct personality I juggle around. Not full-fledged personalities, mind, but they are there. !Lyra is probably the only one that jumped out and graduated to full sentience though, representing the rather obsessive part of me. I tend to not let go of a project until I get bored or the thing dies off on it's own.
Congratulations mate.
