Have you tried printing this (at least a partial) in regular PLA?
I haven't and really should. I've just printed this little puck cut from the larger print and dropped the temps back to 205 and it's returned the outer wall to smooth. I left cooling at zero for the whole print. However, when it got to the top (image 2) the top layers sagged into the infill. as the top of the print is a large, flat disc that's not going to work.
It's become a real balancing act.

This doesn't help with all the problems (although it might help with some) but I can't help but notice you're being incredibly conservative when it comes to support overhang angle - I usually run PLA at 55°. For something a little weirder like this I might want to knock it down to 50°.
Also you should seriously consider getting a new perspective on life. Here's how many places support is required, even at 50°:
It looks even more gruesome from straight below:
I think you need to turn this thing on its head...literally.
Yes, that's still a lot of area that needs support... the bottom shot is pretty gruesome again:
But if you do it this way, the support is all on the outside where it's easier to remove. And more visible, I know, but trees can usually come off pretty well (I've done some really intricate stuff with trees, plus it seems like this material is designed to stand up to a bit of aggressive post-processing). And you don't need nearly as much in the first place. And you have a nice, big, solid circle to adhere to the plate instead of a thin ring. This is at 40° too:
Okay, that's still a veritable forest. But the woods aren't nearly as thick. Nor do the trees get anywhere near as tall. Oh, and literally cuts eleven and a half hours and 14% of the material out of the print.
Also FWIW if you can pull off 55° overhang this is what the bottom shot looks like for the upside down version:
