Here is a synthesizable replacement for one of the catalysts. The other seems a lot harder.
Code: Select all
x = 15, y = 15, rule = Symbiosis
6.B$4.B2.A$3.B.A$2.B.A7.B$.B.A9.AB$2.A11.A$A$A$2.A$.B2.A$3.B.A$4.A.A$
4.2A$7.2B$7.2B!
EDIT: Done! I think it's at least backtrackable by a few generations.
Code: Select all
x = 15, y = 15, rule = Symbiosis
6.B$4.B2.A$3.B.A$2.B.A7.B.B$.B.A9.A$2.A$A$A$2.A10.BA$.B2.A$3.B.A$4.A.
A$4.2A$7.2B$7.2B!
Edit 2: This looks easier to synthesize.
Code: Select all
x = 17, y = 15, rule = Symbiosis
6.B$4.B2.A$3.B.A$2.B.A7.B.B$.B.A9.A$2.A$A$A13.2B$2.A10.B2.B$.B2.A9.2B
$3.B.A$4.A.A$4.2A$7.2B$7.2B!
Edit 3: Simplified a bit more:
Code: Select all
x = 17, y = 15, rule = Symbiosis
6.B$4.B2.A$3.B.A$2.B.A7.B$.B.A9.A$2.A$A$A13.2B$2.A10.B2.B$.B2.A9.2B$
3.B.A$4.A.A$4.2A$7.2B$7.2B!
Edit 4: Actually, I think the tub only requires 2 synchronized gliders at a time to synthesize, due to the pond reaction.
Edit 5: Wait, honey farm.
Code: Select all
x = 26, y = 15, rule = Symbiosis
6.B$4.B2.A$3.B.A13.B$2.B.A7.B5.B.B$.B.A9.A4.B.B$2.A16.B$A$A13.2B7.2B$

Edit 6: Actually, a beehive should replace the block.
Code: Select all
x = 18, y = 15, rule = Symbiosis
