I doubt the regulator would overheat as it's designed to go that low. Rather it's the CPU that should run hotter as i'd essentially be "overclocking" it. Other than that i could look for an AHX variant that's meant for 2.4V. They're not hard to come by, but when you look for a very specific model your option is usually eBay where the prices are heavily inflated.
I think the 2.2v and 2.4v cores are basically the same cores, but the 2.4v one could be expected to have been binned lower, or had more problems clocking up to 400MHz.
I don't expect a 2.4v 400MHz K6-II to be better heat resistant then a 2.2v 400MHz K6-II.
The models for K6-II aren't really that important I think? Or at least not compared to ratings like CPU voltage (usually lower is better when using same core) and frequency (more MHz is better, obviously).
These CPUs are unlocked, so the faster ones are typically better.
Some collectors may want specific models, but when inside a rig the print don't matter 😜
