No! Don’t fill it! I feel in cases like this, epoxy is a bail out. Suggests you’re not up to the challenge.
You know what’s safe. You know your limits.
I wouldn’t use epoxy on those top cracks either. I would just lock them in place with ca.
The big bark inclusion void is just too big to fill in......well, maybe the resin would do it.
As for the crack on the rim.....I've been filling cracks with epoxy, dye, and shavings all this century, maybe longer!.....and, I'm getting pretty good at at it! Besides, with the kinds of exceptional woods I regularly work with, I had better refine my methods of eliminating cracks, or I'd lose a lot more than I do!
BTW: I do leave some cracks, voids, and other flaws sometimes......just depends on if I think leaving it would be better than filling it.....
it's strictly a judgement call. This crack on the rim that is in question however, I feel would be better if I did fill it.

Saving this one looks very possible. Finish turn the top & interior, sand, etc. Reverse mount and remove a couple of inches (?) of the cone shape into a curve. The inclusion will still be there (a feature!) but should be much smaller. We all know you are up to it, Odie! Of course, you will be turning away about $50 worth of your burl.
Definitely something to consider there, Tom
I did another burl very similar to this problem bowl before......and, that one sold......so, I know some people really do like when these naturally occurring flaws show up in the finished piece. This Yellowbox burl is worse off than that one, though.!
