To me the emblems are a secondary consideration as this is probably the best choice anyway.
If we’re staying rainbow then the only purple that’s flank friendly is Sartana - unless you want to strip Proteus (which I doubt?) then she’s not really an option.
The only interesting option, to me, with emblem swapping is to run Zim left wing for cleanse and attack boost…
This means removing emblems from Vela, so she’s off flank - the obvious replacement is C-Magni, which means stripping emblems from Poseidon and/or Boldtusk.
We now want another holy wing - Malosi is very fast but not impactful enough in defence. Norns hits quite hard, which would mean stripping Mitsy.
So that alternative vision is:
Zim - Kunch - Telly - cMagni - Norns.
However… I wouldn’t do it.
As useful as Zim in on attack, that Vela synergy on defence is more powerful than having Magni there.
Magni is worth embleming with that costume bonus on board, but unless you’re running him wing I don’t think you want both him and Vela on the same team.
Norns special isn’t fully utilized on defence, and Mitsy is far more worthy of the emblems in attack.
If you want to keep it rainbow, I much prefer my first option
