...
I was more meaning rules where every prime number is possible as a period.

I suspect you'd have more luck restricting the search to a rule (or set of rules) with an extremely common small ship, several extremely common small SL and which is productive but settles down fairly quickly - i.e. dynamics akin to JustFriends but with an orthogonal small ship.

A for awesome wrote:About the last bit: If you use a diagonal ship instead and search for diagonal offsets for the SL, you can use JustFriends almost as-is with the actual diagonal glider that already exists. This has the advantage that the SL (probably a domino) may be translated a single diagonal while still keeping the ship glide-reflective, potentially allowing perfect speeds, whereas an orthogonal variation would require semiperfect speeds or other pseudo-period speeds.
All in all, it seems very likely that there is a rule in which a particular collision between a JustFriends glider (or c/4 equivalent without S2k) and a domino translates the domino laterally by (1,1) and reflects the glider 180 degrees onto a lane 1hd from its input in the same direction as the domino's translation. The non-totalistic rulespace is huge.
