I was looking for something else, deep in my computer files, and I found something I had forgotton about. By the way -- consider setting up computer files for random ideas that pop up. You might be surprised that crazy ideas from a drunken night years ago amazingly solve a problem that emerges years later.
Quite a few years ago, I dabbled for about a month with something sort of like "One-Level Kokish." The idea was that if the auction started 1C-P-1D-P-?, Opener's 1H would be an artificial relay to 1S (exceptions allowed), after which Opener completed his story. In a Walsh approach, this seemed to make a lot of sense, but I kind of left this alone for, oh, about 10 years.
Has anyone dabbled in that idea? The reason I gave this up was that it seemed like a relatively rare sequence to get concerned about, especially with no competitition, and a relatively non-interesting sequence, in a Walsh 2/1 approach. But, I also imagine that this type of relay might be even more useful in a strong club sequence, or even in a strong diamond sequence (if 1C is nebulous or stacked canape or something).
Eh, probably made the right decision ignoring that idea for 10 years. If the file doesn't get corrupted in the next 10 years, maybe this will be interesting in 2020.
