I believe that this is the initial plan. It seems with a lot of the heel knockouts, TNA management give them a small-time role where they are featured for charisma before getting into the ring to wrestle. Raisha was made so they could test the waters with Alissa Flash... its the same with Madison Rayne and her stay in BP, getting kicked out and rejoining them... its the same with Daffney and her various stints/roles in the company as well before she starts to move on up to something better, assuming when she fully recovers.
So, Raisha was a testing grounds for the later development of Alissa Flash. She is great on the mic, knows how to work and is in the attractiveness range that TNA are looking for.
