Nice request you have.
I don't have any scripting knowledge, but if you know how to fiddle a bit with the HUD, then this shouldn't be too much of a challenge.
For example, the HP meter can simply be pictures of hearts loaded, each one representing 1hp. If you want half or quarter hearts, make those pictures separately. It may be a pain in the butt with coordinates though (And a lot of copypasta to boot).
A bar for the MP is even easier...It's just like the default HUD, you know? xD
