I wouldn’t suggest it unless you’re going to cut a hole for an exhaust fan and a fresh air intake to replace the air in your drying space so it doesn’t get any mold!

Sounds like an expensive rigid tent that’s going to be hard to keep air circulation going in.

You can’t dry or store bud in a deep freezer. Freezing time is what determines how large an ice crystal can form. Slow freeze will create big crystals. Flash freezing creates tiny crystals. Freezing creates sharp ice crystals that puncture cell walls turning the bud to mush.
