Extend Search Engine Integration to work with Kagi

I've recently switched my primary search engine to kagi.com and I couldn't be happier about the experience – if only I was able to see my Memex results along Kagi's search results.

As Memex already supports 4 different search engines, maybe it's possible to integrate its reults on Kagi as well?

Note: Kagi is a paid-only search, and you only get results when you're logged in. However, they offer a 100-searches-free-trial. If you need further testing beyond that I can provide feedback, as I'm on an unlimited plan.

(I'm not affiliated with Kagi, just very happy that, for the first time ever, I've found a Google alternative that works for me)
