Take a glider synthesis that uses the pi created by this fuse:
That should take care most cases, but there are some problematic cases that remain. The ones that I can think of are the block, beehive, traffic light, pond, pi ash, and the constellation produced from this cluster:
Code: Select all
x = 13, y = 12, rule = B3/S23
11b2o$10bo$9bo$8bo$7bo$6bo$5bo$4bo$3bo$2bo$bo$o!
At least some of these can be taken care of by using XWSS predecessors instead of gliders, using different fuses, and/or using different wick, but the block seems especially tricky.
Edit: I just found a way to create arbitrarily large block predecessors where every cell is necessary using a glider predecessor from mirage and an unsupported diagonal line.
Code: Select all
x = 51, y = 51, rule = B3/S23

Another edit: This should take care of beehives:

Yet another edit: I have taken care of blinkers, traffic lights, loaves, and pi ash.
Code: Select all

o!
I don't think that there's anything else in that category that needs to be worried about.
Fourth edit: I realized that I had forgotten about gliders (although they arguably fall into a different category).

Fifth edit: It turns out that the glider predecessor that I used for the beehive solution is a superset of a beehive predecessor.
Code: Select all
x = 5, y = 5, rule = DoubleB3S23
4.A$4.C$.2C$A3.C$2.C!
Luckily, I was able to find another glider predecessor that doesn't have that problem.

I am tentatively considering myself back.
