So in my logic, a trio is actually two aus combined. So basically it goes from Undertale (Only Classic) to the Revert versions of the AUs, to the AUs. So basically, Revert!MTT would just have them revert to being revert AUs, that is, the trio is normal, it's just instead of Dust, K!ller, etc., we have RevertDust, RevertK!ller, etc. Meanwhile, MTTRevert would revert back to Undertale, which DOESN'T revert the AUs, it just fuses them into a Sans with characteristics from all of them. UBTRevert, anyone?
