Wow.
Seems like you are doing the best with what you have for gear. A break-away point for your saw lanyard is important.
Are you using the grigri as a lowering device, or just to tension the speedline? I would avoid both. The shock-loading of a locked off line increases the side-load on a tree with bad structure. A hand-held speedline would be more shock-absorbing.

If the tree sits on a hard pushing-chain (top of bar) it can cause the 'push-back' reactive force, moving the saw toward the rear. This can get the tip of the bar back into the trunk.
I'll push stuff all day long, as long as I'm slow at the end, and know I can push it off, And have a Plan B if something goes wrong.
Bermy, in your case, everything weighs proportionally a lot more, and your leverage due to your reach to push is a significantly less.
I think its a matter of take each operation for the reality that it is, not what is could be/ you want it to be/ how it was every other time. Good work positioning, good judgment, good margin of error matched with the consequences, and work safely. When in doubt, don't.
