While a fun diversion, definitely needed a bit more balancing and tweaking. For example, if you're a rebel Mona is your best choice. Dash, sink into your pool, then don't move. Pick a spot where the water effects can't be seen/heard, and you're now permanently invisible. You're also fast, and you can see the hunter on your minimap so you know when to relocate.
On the Liyue maps, there's no point in disguising as an object; just instead find the closest mountain that's conveniently within the border, climb it ASAP and odds are the hunter will never check there. Even if they get the favor to see where you are, you're on top of a mountain and they're not.
Also, remember that when you spawn in and chose an object to disguise as the hunter isn't blinded and can see you. That was a 30 second hunter round for me. Break line of sight ASAP, then worry about hiding.
So it's fun, but there's a few little things that really should be adjusted for the rerun. Taking advantage of terrain highs and lows seems to help a lot more than clever disguising since the skill that would reveal your direction isn't the default, has a stupid-long cooldown and doesn't convey information very well.
Edit: Also, if hiding in a tree is an option, you hide in the tree.
