It took less than a day, as it turned out -- reported 3201 patterns, none of which included the bait block.
Not that that means anything, of course -- there was still plenty of room in many of those patterns to add a few more catalysts, and any of them might have just happened to settle out into a clean block-glider reaction that would drop a block back into exactly the right place. Here are a couple of the later results, just for the record:

... Irrelevant tangent: I wonder if an H-to-block converter can be found that uses that improbable-looking block-making reaction? It has definitely shown up fairly regularly in Seeds of Destruction, so it's not particularly uncommon. Might be a nice trick to have in the toolkit.
Anyway, my further report is that I haven't searched very far for that replacement block in the block+beehive+eater Hopeful Snark, but I'm going to arbitrarily switch my search allegiance to one of Scorbie's patterns from late last night -- on the theory that
if I happen to stumble on something, it will have a significantly better recovery time...!
Below is the input for Scorbie Hopeful Snark #5, for the old catgl.exe. Again, I'm using this instead of simsim314's new catgl.py so that I can trivially filter for the presence of the bait block. No doubt I should be using CatForce instead, but I'll try this angle and let someone else hunt with CatForce...

EDIT: No luck with either three catalysts or four. Catgl couldn't seem to coax a glider out of the reaction, either, except at the very beginning by sacrificing the block. Here again, lots of angles not tried -- for Spartan catalysts, catgl only knows about (non-transparent) blocks, eaters, boats, and tubs (catalyst #s 1, 4, 5, and 7).
