That is the exact one that I have and the Enidine will work with it. It will look great and the tang does not need removed. Trust me, you would be extremely happy with it.
That setup would work and yes you would need the buttstock screw. I personally would just go for the bonesteel if you're interested in a folding stock at all but don't think that you could go wrong either way.
Is there any way you'd be willing to post a picture so I can see what it looks like installed with the stock? If possible with the stock out and the stock folded
