Seriously; How about giving him a more imp-ish look and call him iMP (or just Imp)?
The old BSDs, FreeBSD and even the Darwin project - which are Unix-like OSes - already got their own imp-ish mascot, it won't be wise to do the same. As a side note, the NetBSD project decided to change their imp mascot to something really different partly because of some displeased christian users (this is one version of the story). The mascot should be culturally neutral IMO.
