Yea, it would take a while before wind picks up some healers. Itaqua (SR, 1000 HP every 6 turns, kinda ho-hum overall) is about 4.5 months or so away. Set/Seth (SSR, is awesome*) is maybe 9 months away.
If you do decide on wind as your secondary team, save up jewels for Set. Sure, 9 months is a long time to build up plenty of jewels... but Set really is that good for a wind team.

*C-frame atk debuff that also debuffs double/triple hits
ailment resistance buff that also provides a barrier (unlisted amount?)
party-wide 1500 HP heal every 6 turns, also wipe a debuff
So Set's kind of like a wind version of Sol. Alternatively, Set is Zephyrus dialed up to SSR.

Other than those two, the only other future wind hime that got my notice is Caspiel (R) in about 1.5 months. Caspiel mainly sticks out for her 2nd skill. A D-frame atk debuff that applies only 5% at a time, but it has a 3 turn cooldown and stacks with itself. 180 second duration, but the wiki makes it seem like each individual stack has its own timer, as it says that realistically you can keep maybe 4 stacks up.
Her first skill's a party-wide 3 turn defense buff every 5 turns. Upgrades from 'medium' to 'large'. That's... a better skill than what I normally expect from an R. Hell, I wouldn't mind accidentally rolling Caspiel in the future; slot her into my wind team over Cronus.
