Carbon steerer crown compatability

I have an on-one fork that I am going to try on a kona unit that i bought to remond me of what steel felt like, and fancy playing round with a stiff front end and what it does to handling (snarf snarf).

Question is: the unit (2011) comes with a dreadful caged bearing headset that looks something like an fsa pig. I bought a pig crown and it sits perfectly, the problem is its a forged solid crown and I really, really do not want to force it down onto the carbon steerer, let alone think of how to get it off.

Have sanded to point of sore fingers, applied grease, etc, but there is no way its going on without some tapping, and then its probably never coming off again...

Thoughts.?

You cannot split the crown of a caged bearing race or can you? Would it not be notchy or are the bearings too well held in place for that?

I also do not like the thought of changing the headset as removing a bottom cup is tantamount to frame abuse and the bike will bear a grudge for the rest of its life, no matter how happy ot is with its super stiff front end...?..

I will upgrade the frame at some point me thinks, and would not want another pig headset, having fsa / campy angular ones elsewhere which afaiac are as good as it gets (no I have not tried Chris King yet)
