I'm glad my Hard mode run got accepted, but I would like to submit some Easy and Normal runs to SpeedRun.com.

Easy and Normal modes would indeed be more faster than Hard and Expert, mostly due to the fact enemies take full damage from all of your characters attacks as opposed to nearly half the damage in Hard or Expert.

If any of the moderators are reading this and decide to add those categories to the Leaderboard, I would more then gladly submit Easy and Normal runs.
