Is this p12 sparker/eater known?

I was experimenting with a known p12 traffic light shuttle, and when I made it push a beehive, I noticed that it can eat a dot and a block:

I didn't see it in the sparker stamp collection.

I know that traffic light shuttles and beehive/loaf mechanisms can make more sparkers, like what I did with my newest p11 domino sparker, so what other low-period reactions or rephasable-looking mechanisms can be turned into useful sparkers? So far I know the beehive/loaf, interchange, sandwich, bi-block reaction, grin, pipsquirter catalyst, the reaction in the p16 beehive hassler, ship+eater, and two-blinkers-to-domino reaction are useful low-period reactions.

in Weak Dot, there is this variant:

I noticed that a B can turn into the same traffic light predecessor in my p10 pi hassler, and then noticed that a block that just got eaten can actually turn it back! The hassler is almost rephasable at p11. It just needs a good dot sparker or other reaction:

However, because p11 doesn't allow for gliders, really, and even though this is a novel way to turn a traffic light sequence into itself, the eater doesn't give much room to turn it back, so I still like the way you discovered, 8than888.
