Plugin releases is for presenting plugins you've written yourself, an you don't even need a plugin for this.
It depends on what exactly you want, there are several ways to do this (and yes, you could do it with a plugin, it's just not the only way)
If you make the transformation a state, then you can have that state add new skills and/or seal old skills. That methode has no sprite change for the actor, but it could be added to any visual transformation you might want.
If you don't have a special battle plugin, the easiest way would be to have the transformation skill call a common event and then change whatever you want in that common event.
