Can I use the bettecreme and cover with fondant?
Rich's 'official' response is no, but I know someone on here said they've used it before w/o any problems. I can't think of who at the moment though.
Try making a small test cake first
I don't see why not as it doesn't change in consistency once whipped. It doesn't seem as if any liquid would seep through and effect the fondant, but you don't know 'til you try it.
Everyone also says never to freeze fondant but I never have any problems freezing mine.
