They seem to exist in the NiMH chemistry [1], but you might have to try a few brands to find decent-quality ones. That said, if you can find ones that work reasonably well, they'd be by far your best option. And I'd be amazed to see them in a brick-and-mortar shop, other than a specialist battery store, and maybe not even then. (If those even still exist, anyway.)
Another potential issue is that NiMH cells seem to run at a somewhat lower voltage than alkalines do throughout the discharge curve. I'm not sure whether that would pose an issue for a device like this; while it probably sips power, it might have a large voltage drop, which could conceivably result in shorter operating time from a cell that runs at a lower voltage to begin with. Still, I'd say it's certainly worth a try.
