As for the tag titles thing, what you should do is just have each partner create a piece of work and then the team that has the most combined votes between the two win the tag match.
Example:
Untouchable Vs. Weebo
Theme: PPV Poster
Choose from one of the two
*Create a Poster for an upcoming WWE or TNA PPV
*Create a Poster for a PPV putting WWE against TNA
