CV Axle Broken During Removal. Frozen to Hub (DIY gone wrong?)

Got myself into a pickle here, rust + bad CV has turned my half-a-day DIY job into at least a full weekend diWHY

When replacing my front passenger strut and CV axle (torn boot):

I undid the axle nut and the bolts that hold the hub to the strut. As soon as I did that, the CV axle and hub lurched forward and to the side. My theory is that the CV axle was likely already failing and the only thing that was preventing it from dislocating was the axle nut.

Unfortunately the CV axle is seized to the hub (first image). I tried hammering it out and PB Blaster.
The CV axle is definitely dislocated (second image).
I'm not sure if I have the clearance to get the CV axle out from the intermediate shaft or the tension to knock it out from the hub (I can't mount it back to the strut because the dislocated CV axle prevents it from going all the way back).
At least I have no tension on the brake lines or ABS wire.

Figuring out how to remedy this situation (I don't have many crazy power tools and what not):

Currently thinking of removing the knuckle with CV axle:
  1. Try to knock off the axle that's in the intermediate shaft to free the CV axle
  2. Remove the caliper, remove the rotor, remove the knuckle with CV axle attached
  3. Replace knuckle assembly with new CV axle
At this point I feel that the hub is so seized, it may not be worth saving (even if I get the CV axle out, good chance the threads are worn given that the tension was holding the axle joint together).

Anyone have an ideas of how I can make this DIY job easier?

Thanks. Rust welding makes everything tough. I still have to remove the caliper, rotor, and lower ball joint. The pictures are as it currently is, I wanted to get some opinions before attempting anything else. I tried to reattach it to the strut but the cv axle does not budge (I can bring the hub up halfway only) because of how it seems to have slipped out. bringing it to a garage seems like a good idea. I just hope all the forces here dont damage the splines.

I managed to get the knuckle popped back in place and to the strut. Put the transmission in neutral and rotated the hub until it “clicked” physically. Then 10 mins of elbow grease got it back. credits to YouTube.

Going to get a rotary hammer tomorrow. If that doesn’t work it’s axle out with the knuckle.

when reinstalling the new one either lots of grease on the spline or anti seize

Do you grease on the spline to the hub or spline into the transmission/intermediate drive shaft?

The other question is, could the axle already have been compromised (although this disassembly likely did it no favors) because the boot has been torn for a while? Some clicks while turning and accelerating.
