it would take a serious stroke of luck to convert it into a clean HWSS, let alone regenerate the pond at the same time. The reaction is mostly inside the reaction envelope of the collision --
which suggests to me that no tamed version of any sort was known.
A few minutes of toying with manually placed catalysts however reveals that a great variety of objects with a hook indeed suffice to clean this up to give an output HWSS... Anyway this seemed too easy to have gone undetected for years, so maybe this is in fact known already?
Interesting question! Speaking only for myself, I didn't know about the pond-and-aircraft-carrier HWSS turner, or its other clean variants. It's possible that I did know about it once and have since forgotten, but I don't think so.
There's probably some confusion about terminology here, though. The question I was answering above was "
... how would I go about searching for a reaction that turns this into a clean HWSS reflector?" And
reflector means that whatever the HWSS hits will return to its original configuration. So that's the question I was answering; it's possible that the question was really about turners, but I was thinking it was about adding catalysts that could produce a clean HWSS output
and rebuild the pond directly.
The structures that you and wwei23 have constructed are
one-time turners -- fairly good turners, but they're not reflectors, and they're not very easy to convert into reflectors. To do that you'd really want to end up with an HWSS plus some other signal output, which could then be split into many signals to rebuild the bait. By the time you're done with that project, the circuitry is probably huge -- almost certainly bigger and slower than what we have already for
HWSS-to-H plus H-to-HWSS... or even, HWSS Heisenburp plus G-to-HWSS, plus an HWSS eater I suppose.

Towards the construction of a stable reflector, no especially simple still lifes seem to output a G or H to be fed into bait reconstruction circuitry. Adding third catalysts would probably achieve this, left as a future exercise (wwei23 already posted some on the wiki).
Here the only piece of terminology I'd argue with is the use of "catalyst". If something is destroyed completely and rebuilt with totally separate signals, it's usually called a
bait, even though it is technically also a (very slow to recover)
transparent catalyst.
A Survey for Someone
Here's something that has not to my knowledge been done yet. All
common well-separated pairs of common still lifes that fit inside 12x12 have been hit with all possible gliders, but they've never been hit with all possible *WSSes. There are some results for *WSS
outputs for the
8x8 case with no maximum number of objects, but nothing for starting with an input *WSS. So the equivalent census run could be done for hitting those same constellations with *WSSes, and seeing if any *WSSes come out. No doubt there will be lots of clean glider outputs, too, if it seems worth collecting those.
If anyone wants to compile a *WSS-input stamp collection for the 12x12 constellations, let me know. I have most of the necessary scripts lying around somewhere, but they'll need to be generalized and updated, and checked in somewhere so that they can be used for hypothetical future more ambitious enumerations of constellations.
