advice on squad

SubmarineMan

Hi everyone, I have a decent ish squad however I feel they maybe a bit of mish mash rather than a proper squad who can work well together so I thought I'd see what you guys think.

My squad consists of:

Main squad
Luminara 67, 7*, lvl 8 gear, 5360 power
Fives 67, 6*, lvl 8 gear, 5127 power
sidious 67, 7*, lvl 8 gear, 5093 power
QGJ 67, 5*, lvl 8 gear, 4719 power
Kylo 67, 7*, lvl 7 gear, 4599 power
Luke 67, 7*, lvl 7 gear, 4565 power

Currently working on:
Old Ben 64, 5*, lvl 5 gear, 3200 power
Dooku 67, 4* nearly 5*, lvl 5 gear, 3186 power
Leia 60, 5*, lvl 6 gear, 3350 power
Daka 56, 4*, lvl 5 gear, 3000 ish power

I've heard that QGJ and old Ben could become a good partnership now but I have old Ben ar 5*, would that be enough?

Thanks for reading

Mmmmm ok ty for your help everyone lol.
I'll ask something else instead.....

Cad bane and leia are 6 stars now and kit fisto & aayla secura are now 5 stars. Would any of them be better in my team ahead of the chars I had listed above? Despite the 1-2 star difference

Thanks
