Skywalkers take sabers, then Protags stomp in Force, and take all-out.
In Force-only, Anakin and Outlander probably goes nowhere fast, given that HoT's held his own against far superior Force users. Luke doesn't have the feats by this point to handle 'Thor. Cade gets wrecked via sorcery from Nox, and Jaina probably beats Wrath, but quickly loses to Nox's sorcery.
For all-out, Anakin and Outlander go at it for a while, they'll probably finish their fight last. Wrath can likely hold his own against Jaina for a short while, but inevitably loses. Nox slaves Cade with sorcery again, then goes and helps Wrath, meanwhile 'Thor beats Luke via their Force gap, then gives Outlander a hand with Anakin.
