My suggestion is a Dremel with a cutting disc or a burr. Doesn't matter if the axle gets a light touch if you go a bit too far through the inner race.
I'm about to do same job but on the outer bearing therefore will likely have to trash the wheel, will try not to though.
Sometimes you have bite the bullet and destroy an otherwise good item to get the bearings off. I hate having to it but it necessary at times.
And referring to the ATF/Acetone mix the only draw back so far is that I got to remember shake it up well before use as it tends separate sitting awaiting the next use. But it has been working better than the over the counter penetrating fluids I tried in the pass like PB blaster and WD-40.
