Wasn't it hinted that Dan was also Choza's sensei?I know that it was never directly confirmed, but it's still unlikely.

and yes, there was a Sarutobi jonin who could've taken over the new Ino-Shika-Cho, and that's Konohamaru. If a "Sarutobi being the sensei of Ino-Shika-Cho" was that important, than Konohamaru would've trained them, instead of him training Boruto's Dad's Son team.

So i don't think that it's such an urgent matter for a Sarutobi to be the Jonin in charge of I-S-C.
