You could always throw together a show team for an in-gym showoff (so that all the kids can show off their skills), but honestly I would not recommend you doing that all season at actual competitions.
Per the rules, you would essentially have to go out as a (sad) Level 3 exhibition team...............
"Teams that perform in exhibition or evaluation only at an event must adhere to the USASF Age Grid and Level Rules as would any other team. Exhibition or evaluation only status does not allow a team to violate the safety rules or age restrictions that have been put in place for all athletes. Any exception to this rule must be obtained in writing from the USASF. "
Some things to think about.............
A. This is competitive cheer. These girls are signing up to compete. I would be concerned that:
(assuming they are older than tiny age)
-the parents will be unhappy spending so much money to just have their child do a routine for no result
-the kids will lack motivation because they are not pushing to improve their placement throughout the season
-the kids will not get the experience of a true competition. Gracious winner, gracious loser and all in between
B. As I judge, if I saw a show team throwing level 1 skills mixed with level 3 skills, I would be confused. If I had never seen your gym compete before, questions like: Are they trying to be a level 3?:confused: Do the coaches understand the rules and scoresheet? Are they a really small, new gym that doesn't know what they are doing yet? etc............would all honestly run through my mind (ESPECIALLY if this was a competition past regionals season). It just makes your gym name mentally associated with (putting it in a nice way) "small, not as professional, etc.".
I would either:
-make these girls the absolute cleanest, beast team of 6 that level 1 has ever seen (1man or 2man your socks off)
-have some of the level 2 girls cross over if allowed at the comps you compete at (to max pyramid)
-recruit more and then put these girls in the prep division (assuming the new kids would be more inexperienced)
