you may be able to run a variation on this setup: https://deadwoodjedi.com/speed-tunes/pavos-krisk-and-lydia/

mausoleum mage can be used in place of brogni and i'd suggest replacing lydia with heiress, plus any dps champion. i can't say for certain that it will be able to 1 key with those substitutions (this is not a comp i am at all familiar with), but it seems like your best shot.

Thank you, its worth a shot. Isnt pythion better than mausoleum mage?

totally missed him the first time around; he probably would be. 

that said, he's better than mausoleum mage everywhere so mm still might be the way to go if you want to avoid locking pythion into a cb-specific build.

I would avoid Pythion unless you had no other options. He's just too good to restrict to just a CB team.

furthering that point, I'd rather stick to a Helicath comp if we can. would like to free up krisk and mithrala as well. 

Is there even a particular reason you want a 1 key UNM? a 2/1/1 for UNM, NM, and Brutal is good enough...

And what would you suggest to free up krisk?

Because usually a dont have time in the morning and due to geomancer i have to wait till affinity to go UNM and that combination restricts me to only 2 key usage, so i miss the NM boss. If i was able to 1 key UNM, i can do both every evening
