You can also use a blinker-puffer halfway between and behind two others' offset by 18 cells to destroy their blinkers and create its own phase-alternated ones a cell further behind (in case you want the sparker separation of two but the output of one and want it to be more compact than putting two blinker-destroying spaceships before the new blinker-trail-making one (destroying the output can be done more compactly by two of the period-8 spaceship than halving it first, so it's only practical if you want to half it)), here are three spaceships (varying in tail, the two known blinker-puffer reactions (the leftmost one is still xq36 but larger because three explosions occur simultaneously) and one
xq8_1qie blinker-destroying spaceship):

Edit 2: From looking at all yl72s,
yl72_1_12_210448f944106547e334925b86a97147 is a rake based on an interaction between a blinker puffer and a LWSS, generating a LWSS/36 cells and glider/18 cells at c/2 (beating the glider/24 cells in the main post but not the LWSS/12), here it is with a xq8_1qie removing its blinker trail.

Here's a c/2 LWSS/18 cells siderake also (from
yl72_2_48_53b0f96fbc303be5944e374cea046614). The xq8_1qie can't be moved to higher up on the left (to reduce population) because without every second blinker, the explosion at the bottom creates mooses as well as blinkers.

xq72_1qiezsy4sy4sy4sy5oc4szysciiic111 is the most common blinker-puffership because two instances of it have a 12-cell predecessor.

is a glider/54 cells backrake, but produces blinkers and mooses behind it that destroy its gliders. In finding a stabilisation (most likely not optimal, I only put in and moved around blinker-puffers until its exhaust was entirely blinkers), I discovered one of them was redundant, but creates another backrake glider in the opposite direction. If you allow the glider from the right side to hit it, it makes explosions that create gliders in a staircase shape and leaves only two blinkers in separate lines every 36 cells (that can be removed with a xq8_1qie). Here are the three versions next to each other (with a moose glider synthesis and destruction).
