I think he wanted to post about the possibility of a R-to-H hidden in there, I tried a few wierd things, and there is plenty more reaction that could suppress the B instead of the blinker of the original reaction. And only found near misses, yet:

Actually, the B erase the outstanding block already, but needs to be further contained as it is backfiring back toward the R location, a simple eater does not cut it, but something else might, otherwise one needs a lucky block factory that fit there, or one that move the block into some other still life... possibilities yes.
Addendum:
Actually fixed it, made an F207, but it's repeat time is 327 sadly:
