If you get into an accident under these circumstances, any insurance you have (whether through the AWD, purchased from Avis, through a credit card, and possibly even from your own insurance) will be void and not cover you. While you could save a few $$ on the rental, you're opening up a can of worms for issues down the road that could be many100-1000x more costly than what was saved.
Besides that, announcing that you are thinking of committing fraud is probably not a great idea if your FT handle matches the name you plan on renting under and/or the airport you are next flying into. Just sayin.
