Quake Weapon Modding? I haven't a clue.. what about?...

[optmusprimenumber]

I dont mod or hack games. I do very much enjoy using them though. I guess I'm just wondering if for instance Quake 3 weapons can be put into Quake 1. And more broadly, could one make a weapon pack that features the weapons from Quake 2 and 3 and have a weapon options menu that allows you to pick which weapons are used? I've seen other weapon packs but they don't really cut the mustard for me. The internet doesn't seem to share this interest. Is it wicked hard or what?
