You're more adventurous than I imagined! And I never realized that dry ice makers were so available.
Back in the late 1990s, I made a nitrous liquefier to experiment with mixed nitrous/fuel monopropellants. I was successful in making and testing liquid nitrous/propane and nitrous/ethanol blends. The latter burned very smoothly, and showed no shock sensitivity or other nasty traits. So did nitrous/propane, though I found that the gaseous mix could propagate a detonation. Addition of a small amount of CO2 would tame that. Isp for the nitrous/propane was more than 300 seconds.
I wouldn't try those together n a dry ice maker, naturally, though a reverse hybrid with solid N2O and propane would no doubt be really good. Ammonia would, of course, not contribute to global warming (as long as no N2O escaped).

Has anyone tried ammonia in this configuration, Making grains of N2O with a dry ice maker is easy and the density is impressive. Additives are also proposed. Any work in this area?
Thanks.
