Bypassing other AVs would really be a 'nice to have'
Further, AV is inherently a "catches known threats" technology, as much as any AV may pretend otherwise. Some people will always get owned but by virtue of those users' AV picking up samples the sample will eventually make it to various AVs.
If your goal is to avoid AV bypasses, I'd suggest changing your goals. Instead, treat AV as it is - a technology for finding known bad things. If you want to avoid unknown bad things you need to take another approach.
ANYTHING that touches lsass.exe, no matter how, will trigger AV these days.
Go and try to compile your own customized version of Mimikatz, unless you are malware developer, you will not manage to get one that doesn't get flagged.
