Jakks fatal four way series christian question

Hey guys, so recently ive been buying several of the old ra era guys and building my collectuon from 2003 up till the end of the line. Some noticeable ommissions from the ra line early on for me were Mark Henry in his white and red attire, triple h in his red and his blue attire, and a long hair christian. I've completed the first 3 and now I'm working on Christian.

My question is, I was looking at the jakks heads can done of Christian with long hair, and aside form the ttl Christians and the fatal four way Christians, those would be my only options and the fatal four way scan looks much better.

Would the head from the fatal four way figure be able to be removed? Or would I have to cut it off of the figure? I can't tell from pictures I've seen and wanted to get you guys input. I know some modifications would need to he done regardless but just wasn't sure which scenario I was looking at. Also, what's the scale of the head to the regular RA guys scans?
Thanks again guys. I would have posted this in the customs section but it it always seems dead over there to me, and as a jakks figure fan I want to help keep this board alive.
