If Delta can go toe-to-toe with adult Naruto, even if the latter's holding back, she can basically solo two Akatsuki two man cells on her own. Not to mention Jigen was estimated by Kawaki to be on par with SPSM Naruto, while Kashin Koji is hyped up to be, at the very least, on Delta's level. We don't know much about the other living member but we are to assume he's pretty strong too.
Now obviously I can't come up with a battle scenario since we barely know anything about Kara, but with all the hype surrounding him, it's safe to say Jigen himself could solo the Akatsuki with mid to high difficulty, provided Kawaki's powerscaling is correct. Shin's inclusion makes no difference - he was barely above base Sakura and would be the first to get his shit kicked in.
