Alternative for Duel of Wits

Probably someone proposed that, but I’m new to Burning Wheel and don’t know if that is the case.

I figure out some alternative for Duel of Wits and I’m curious what do you think- especially people that better know system.

It’s similar to Blody Versus test but first each side roll for their skill and compare results. Someone who wins add difference in results to their next test which is exactly like bloody versus test - each side choose dice for attack and defence (side which win previous test have more dice equal to difference between each test). Wining this test (not getting “hurt”) means you have what you want. If each side get “hurt” it’s mean compromise, and of course loosing means your opponent gets what he wants. I think the first test from witch you can get extra dice overall increases probability for compromise - which is good.

What do you think?

P.S. It may sounds confusing, but English is not my native language.
