Different Bosses - Can't really comment as I don't know all the current bosses in-game. Plus doubt I'd remember all the old ones anyway, especially their names.
More boss spawns - Not sure that would be a good idea, as it'll just mean more mats in circulation.
Randomise things - Probably the best starting point.
But any change will need reviewing at some point as it may require further tweaking.
