This is a non-issue, with all due respect.
TONS of non-SAG movies are made every year. Non-Union work is very, very common...heck, I can't even count how many horror movies alone I've seen this year that weren't SAG related.
Indie feds are like indie movies...if you aren't going to treat Die You Zombie Bastards the same as you treat Avatar then you don't treat a local indie fed the same way you treat WWE.
At the very least wrestlers should be treated as stunt men. If some dude can get a SAG card for walking behind teenagers with a knife and pretending to be pushed out of a window in a movie, then surely WWE wrestlers should qualify.
