Would life force not translate to Yang chakra, or part of the physical energy that makes up chakra? Hence why an extraordinary life force would also result in inherently larger chakra reserves. Which is why someone like Kakashi mentioned that certain clans have different levels of chakra and how he could never do enough training to reach the same level of chakra that Naruto was simply born with (this all occurring when they were learning Rasenshuriken).

Maybe I'm not remembering that correctly, it's been a while. Just figured I'd throw in my two cents on the debate.

On the subject of what OP posted though, wouldn't a more legitimate source of Konohamaru's large chakra source stem from his use of Rasengan and Shadow Clone as only a genin? The latter technique being described as Jōnin-level, and still having enough chakra to then use an A-rank jutsu like the Rasengan to defeat the Naraka Path. Still don't think that necessarily means he's got Uzumaki blood though.
