Activate 110 and there won't be a split, problem solved and everyone's happy.

A "chain split" is not possible here. You can only have a dead soft fork or BIP 110 conpliance. Also, this is literally always possible by miners but nodes keep them from changing the rules (by validating their work.)

There is a religious fever going on in 110 land, try talk to them. They are angry, big feelings.
