Flier Emblem with Myrrh and STiki(Y) a bad idea?

I'm getting ready to stand up a flier team on my secondary account (for PvE & Assault, not Arena*). At this point I only have Myrrh committed, and I was planning on pulling for the other units on upcoming banners.

I want a bladetome flier, and it seems that Summer Camilla fits the bill. I was planning on pulling for her before the banner ends, so I was thinking about what red to run with Camilla and Myrrh. It just occurred to me that the new Summer Tiki is one of the best fliers now, and I wonder whether she would be a good fit. She shares a banner with Camilla, so that's convenient.

With Tiki's high BST and speed, she runs a mixed phase set pretty well, but I worry that having two flying dragons is a bad idea. I was going to patch up Myrrh's arrow vulnerability with an Iote's seal while relying on blues and reds will take care of Falchions anyway. But with Tiki, I worry that might not work out so well.

Thoughts?

*My f2p Arena team is fully built and just need merges, so I gotta spend some orbs to find them. (ATiki, Effie, Sheena, incidentally.)
