Haha! If only my DM would go for that... Maybe I can convince him the Artificer may have bows? Ah well, guess ill be juggling bow/implement/sword then, as I'm not a fan of that particular paragon path, thanks for the help guys!
Take the disembodied hand familiar (or the rakshasa claw upgrade). It lets you retrieve or stow any item as a free action. This will allow you to freely switch between bows and wands when using weapon and implement spells.
Or the MC feat that gives you cantrips, and keep a mage hand active for free switching of your (now FOUR) hand-held items (after all, you just took a wizard MC, I expect you'll someday want a wizard implement). If we were still in 3.5, this build would require ranks in Perform (juggling).
