Idea for the knight model and ghost

so I have an idea for the knight model so I like the knight potion thing you get from milestone but there should be one that just a model and not use the special animation and use the default rig it would also be nice if you could wear items with the knight model and you can use it in ball race and virus ect same with the ghost model I like the ghost potion that acts like the one in game but there should be one that just a ghost model like in GMT and you can wear hats and use the jetpack and use it in other game modes
