Oh yeah 100 billion %
Sure, she enjoys blowing up on "accident" and getting humiliated to kingdom come (as long as it's not around her art peers, the fear of losing her credibility (and, by extension, her career. This fear is utterly impossible because other artists are weirdos too but it still limits her in that regard)), and she's used it for practical purposes or in her art at least twice...
...but y'know what? Sometimes you just gotta take it easy. Hook up to a tank, get enveloped in a warm airy hug from within, and just let a few hours pass, alone with her happiest thoughts. It's a nice way to relax if the day's been stressful or if she just wants to have some time to herself.
Sometimes, on warm nights, she dreams about filling up with helium and floating through the skies on a sunny afternoon. Not worrying about who's watching or how she's going to walk back from here, just appreciating the cool breeze on her puffy deer flesh mixed with the pleasant heat from the sun. Those are always pleasant dreams.
TLDR: Definitely! Being a big ol' balloon is probably comfy as heck, so I don't see why she wouldn't. She'd probably love that if she was careful about it.
