Very nice collection! Interesting that boats and longboats seem to be so over-represented in the results -- not surprising, really, since they're both turners on their own.
My favorite splitters so far are these:
x = 38, y = 183, rule = LifeHistory

The top two can be dropped in to a glider's path to extract a 90-degree glider without changing the original path. This may come in handy for self-destruct circuitry somewhere or other. The top constellation actually speeds up the glider by three ticks, where the second one slows it down by 42 ticks.
The last constellation seems as if it might be the cheapest splitter -- lowest population, fewest gliders to construct -- and it has other nice properties: it's both an edge-shooter and a highway robber, so it can pick off a glider on a target lane while allowing gliders to go by on an adjacent lane -- and return a glider to the original lane if needed, with an adjustable delay:
x = 81, y = 69, rule = LifeHistory

I'll check my block+object database and see if this is a really cheap constellation to slow-construct (with P2 intermediate targets, anyway).
EDIT: Not bad -- 7 or 8 P2-slow gliders can produce any orientation of the block-and-boat splitter, starting from a simple block:
x = 8482, y = 5253, rule = Life

I can generate lists of lane numbers for these recipes (and a few more -- this isn't quite a complete stamp collection) if anyone's interested. None of these are much use for a P1-only project, I suppose, though there are a few recipes where the last target is another P1 constellation.
P.S. There weren't any 3+ glider outputs for 2sL constellations, were there?
