Impressive! Of all the rules I would think might have spaceships, B3457/S1238 would not be one of them.
Random patterns in that rule expand quickly with blotchy internal chaos. 2c/4 ships are often the easiest ships to find in such rules. That particular ship was the only thing found in my width-8 2c/4 sweep of B3 rules without any known ships.
I have been examining a few rules with B3456 and without any of S123. Such rules often favor odd-period ships with displacement 1. I recently found c/7 ships in B3456/S45 and B345678/S47. It turns out, they also have relatively small c/9 and c/11 ships:

I also took another look at B345678/S48, in which I failed to find a c/7 ship earlier (searched up to search-width 8). This rule has a reasonably-sized c/9 ship, which is the first known ship in this rule:

Edit: I completed searches for period-6 c/6 orthogonal ships with odd and even symmetry of search-width 7 for all rules in which no spaceships of any type are known. Unfortunately, I didn't find any ships.
Edit 2: Here are c/5 ships in two adjacent rules. The B3456/S4578 ship is the first known ship in this rule.
