Wasn't it hinted that Dan was also Choza's sensei?I know that it was never directly confirmed, but it's still likely since Dan was in Jiraiya's generation, and Jiraiya trained Minato, who was in Choza's generation.

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's 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.
