I know there's a game idea board/wish list, but I think if I posted my idea here it'd see more discussion.
My idea is relatively simple: Having henchmen that the heroes can hire in town. These would be "one shot" lackeys, with a profile similar to that of monsters. Fixed attacks, special abilities, etc. They would be relatively weak, but would provide some useful support before they're hosed by the monsters (they don't come back from being dead) You could even have one henchman that's simply a porter... Sort of a variant of Mata and Kata, where he can run around the dungeon carrying a couple items to be handed off to the heroes.
I can already see several potential problems with introducing this concept, but I'd like to get your thoughs.
