Halfway between two Life-like cellular automata

[confocaloid]

Pick two Life-like cellular automata that are only one neighbour-counting condition away from each other. Unpack the differing condition into isotropic subconditions. Choose an isotropic CA that is midway between the two Life-like CA, with its definition including half of the differing subconditions and excluding the other half.

There are 252 rules "midway between" B3/S23 and B35/S23. (Every such rule includes exactly five out of ten Hensel conditions from the set {B5c, B5e, B5k, B5a, B5i, B5n, B5y, B5q, B5j, B5r}. Rules without B5n support the xq4_153 glider.)

One such rule has a sparky diagonal 3c/34 spaceship which can be used to construct glider rakes, a p220 oscillator which can be used to construct a glider gun, and p38 and p30 oscillators. Is there a stable glider eater?

No stable eater yet, but I found a rephasing G-to-TL and a p36 right off the bat:

I'm not sure how to handle the B4/S4 cases best (13 is not divisible by 2). One possibility is indeed to exclude them as "offtopic". Another way is to include as many subconditions as possible, while still avoiding minuses in the canonical rulestring. That means including =7 out of 13 subconditions, with 1716 rules in the set.
Here are some such rules, which are "almost halfway between" B3/S23 and B34/S23:
