The only good all OT only lineup team with good synergy is:
CLS, Raid Han, Chewbacca, Chewie&Threepio, and C3PO.
Princess Leia is decent with R2-D2. Old Ben is another good one but I prefer using the whole team
mentioned above.
Wedge and Biggs is fun to play with but they are pretty weak and easily brushed aside with a decent synergy team. But if you put them in a Mon Mothma lead squad...
JKL doesn’t even have any synergy with most of LS OT toons apart from Old Ben and Hermit Yoda so not what you are looking for at the moment so you have the right idea of leaving him for now.
