Challenge, Sasuke(and friends) Vs Smith (and squad)

[Red]

Question: since trunks is already in the nexus, could he fight someone in the fight, after the fight?

Interesting question, cause of he's not a valid target for the fight, does it make sense that he could be involved? Certainly an interesting question. I can't see why NOT?

Trunks formed a relationship wit orihime during the saga, and Sasuke is orihime partner IC so it wouldn't make sense to abandon them, but I'm also aware I can't enter with both characters.
