Transforming Skill help needed. Maintaining LVL and timed.

Complete and utter Noob trying to do complexities... (Using R2K3)

OK i am about to rip my hair out, i looked around but i cant seem to find anything.
What i want to do is this,

I have a class system placed in game with selections for warrior, druid, healer etc. each with their own skills and abilities.
But each class must earn the abilities, so i have put in a consentration skill for each and based on that they progress their abilities.

Im having troubles with the Druid though, I can not for the life of me figure out how to have a trigger / switch / whatever that when he uses the skill (Transform (Beast) or Transform (Feline)) *Only in battle* that it will change the character into the creature, both having very specific attributes. But the Transformation must take the caracter level and set it for its own lvl

IE. Silent BOB is LVL 23 when he uses the skill the New form must also be a LVL 23
It also needs to share XP so if the battle is won with the transformation Silent bob gets the XP and Full xp not split amongst party members, and any items gained.

Any Ideas?

ok the more i look at it the more i think this cant be done on RPG Maker 2K3.
looks like only way would be in XP or VX and using scripts but dey not freeware only 30 trials so me no can work with.... it sux....

But if anyone got suggestions on what i can try please let me know
