Since Legends is based somewhat on the Belmont's Revenge engine, I sometimes wonder if it might be a "simple" to hack Legends so that you could play as Christopher Belmont. Well, I'm sure it wouldn't be too terribly easy, but it might be reasonable and kinda fun? Any thoughts?
It would be fun to add Trevor Belmont as an unlockable character and make it so that he could use all of the subweapons that Sonia was able to find in the during her quest. You could use Chris's sprites, give him the holy water, axe, and boomerangs from the US and European Belmont's Revenge game and use Sonia's Wind Soul for the Pocket Watch. The Dagger doesn't appear at all in the game, so it'd need to be made from scratch. Perhaps the Saint spell could be used for a Dagger? The subweapons should be selectible like Sonia's souls, the icons for the weapons are all nicely available in Legends. He shouldn't be able to use the flame whip.
Anyways, I always thought they should have let you play as Trevor as a bonus after beating the game.
