Is it possible to merge several big catalog mods?

I used this tutorial - https://www.nexusmods.com/reddeadredemption2/mods/2157?tab=description to merge enhanced rdr, why ems, and rdo

I also found this tutorial - https://allmods.net/red-dead-redemption-2/effects-and-changes/the-trifecta-merge-v1-01/ to merge EEE, whyems, and 1899 firearms

Lastly, I found this light merge - https://www.nexusmods.com/reddeadredemption2/mods/2465 for distinct gunsmiths and whyems, 

Is it possible in the slightest to somehow get a game running with enhanced rdr, why ems, rdo, EEE, 1899 firearms, and distinct gunsmiths all at once? I can do without distinct gunsmiths if that's not possible but getting why ems, enhanced, and 1899 is what I'm trying to do.

Just having enhanced, rdo, why ems, and 1899 would work as well, if using distinct duo isn't possible as I'm pretty sure it moves all why ems items into the trapper's catalogue
