I would actually be fine with separating rituals from other spells. They feel different anyway, and no one in my groups wastes a spell slot on a ritual. Make them castable by any class with an appropriate DC Arcana check, maybe starting at 10 and increasing by 2 per spell level (just off the top of my head). Ooh! Maybe an optional spell failure random table with hilarious effects!
Good idea. Maybe bring back ''martial pratices'' as non-magic ''rituals'' for non casting class. There were some good ones in 4e (and 3.X IIRC)
