A RPG game?

English:
I have an idea of creating a RPG smbx game, my question is:
It's possible to do that?

Español:
Tengo la idea de crear un juego rpg de smbx y quiero saber si es posible hacerlo

It probably is, but it will be very, very technical, and I tried and failed on the 2nd week. (P.S If not done, you can lock up Mario and the Great System cloud) (Unless someone is working on it, delete it).

Someone I saw on Knux's forum made graphics for M&L: SS in smbx.

the blocks are in the link below
