Is it okay to have a mixed squad?

I like this squad because there are mixed synergies to benefit the different characters.

Not sure you understand synergies friend! Synergy (generally) comes from teams composed of characters of the same affiliation - Empire, Sith, Jedi for example. Mixing characters from different affiliations will result in zero synergy.

If I was you my Arena team would be - Wedge (lead), Biggs, OG Han, R2 and Leia. Huge offensive team right there. Maybe swap Leia for Kanan if you feel you need a tank...bear in mind R2 is something of a "pseudo" tank already.
