I still use a pen/crate combo, so that won't help you. But I can tell you this: My spoo Peggy didn't get destructive until that age. I thought I'd hit the jackpot! So don't assume it's separation anxiety. A secondary chewing phase is very common, and it sounds like she might be getting more freedom than she can handle.
If you don't want to go back to crating (and if it was a negative experience, you probably shouldn't unless you've got the patience to start from the beginning) you need to do some hardcore puppy-proofing. She can't be allowed to make any mistakes.
This is for the sake of your stuff and sanity, but also for her safety.
