I did some research (to prove my point) and learned that:
āBackportingā items is kind of possible but not really and especially not on a paper server lol. You have to either:
Find a mod that is compatible. Thereās literally none that work on paper.
Code your own mod, build your own port, and do a lot more coding
So yes it technically would be possible but itās not as simple as u think.
And even after all that I can guarantee u that it would be super buggy
Even if I could easily add maces and stuff I wouldnāt.
