How Can I Make Cleric's Able To Use Bows?

I really want to dual-class a Ranger (Archer), to a Cleric in BG2, however as many of you know, it is the only dual-class option, and quite possibly the stupidest of them all, considering archers get GM in bows, and then if you dual to cleric, you can never use them again -.-, which makes sense right? I am an archer, i master archery, then pursue being a cleric and focus my energies there until i am proficient at both classes, shit i forget how to use a bow :(...lol

Too me its unfathomably unrealistic, is there a way i can change the variable which disallows certain weapons for certain classes, it would be awesome if i could just allow class "Cleric" to use all bows in game (Or if i could just make CHARNAME able to use all bows), i understand i could simply force the weapon on my Char, but then i can't switch bows without shadowkeeping again and "ain't nobody got time fo dat".

So if anybody could offer any mod/hack/advice/etc that could make this happen, i would appreciate it, thanks
