I would start with a sequel to Legion of Three Worlds.
Have a 'crossover' between all the Legions again.
Then when it's all over, the Levitz Legion takes center stage and expands with a few members from the others, and grows forward from there.
Yeah, there were a few legionaires from that book I’d like to see again.likewise, there are a few characters from the bendis legion I’d like to see stick around.
