Ball Joint Replacement - in RC Forged control arms

[Mossyoakglock]

I need to replace my lower ball joints and while I have everything apart, I'm going to replace one of my upper ball joints in my RC forged UC. A while back I noticed the boot was torn so as a temporary fix I replaced it with an Energy Suspension boot. It's a close fit and keeps the grease in but I want to replace it the right way. 

So, my problem with replacing the balljoint in the RC forged arm is that I cannot get a cup from a press to sit. RC's design prevents that from happening due to the angle of the arm against the balljoint cup and the fact that the lip is very narrow and rounded makes it almost impossible for it to sit correctly. I will need to press them up to remove. Pressing them back in and down shouldn't be an issue.

Has anybody replaced a balljoint in the forged UCs? Since I likely won't be able to use a press, do you think an air hammer will work to push it out? I don't want to have to fully remove the control arm since taking it to a shop to be pressed out/in is not really an option. 

For those not familiar, here are the arms where you can see how the angle prevents using a rented press.

Bump...

 

Nobody has these control arms or seen them? Any suggestions on removing the ball joint without having to take them to a shop?
