Wedge is one of the best all-round LS leaders, but it's best with an all-rebel team. Since it looks like you're farming in preparation for CLS already, I'd say you're already on your way to a great rebel team. Lando, Leia, and STHan are probably closest to being done since they're farmed from different places, but you'll probably want to replace Han with Old Ben once you're done with him too.
I ran a real patchwork Wiggs team for a long time, so I know exactly what you're going through.
I don't like the idea of splitting up Phoenix so I'm not going to suggest you do that, but I do think you should either farm your classic CLS rebels to go with Wiggs or Phoenix, but don't try to do both. Finish one, then work on the other. You'll have 2 excellent rebel teams when you're done (close to 3 actually)
