If you can find a garage with the correct press, they would probably press it out for a small fee.
To get it hot enough, it would probably destroy the bearing as you say...but bearings are cheap enough.
You really need a press to fit the bearing though.
You could get a full hub from a breakers yard if necessary.
Thanks for the reply that is what I have done, if anyone wants a hub with a stuck in drive shaft let me know
