Lets see. In my experience it can be iffy to let lps touch each other period.
My acans are all happy to touch and thrive, my scoly does not like anyone (although never touched anything too long as I tend to catch if having issues and move. Acans were nearby with little issue though.
My lobos in the past have been mixed. I had some that could touch each other, some that killed everything even other lobos. Crazy one now cannot touch or be near anything without trying to kill it.
My hammers, frogspawn, were mostly okay being close. My duncans hated touching things and would shy away and die. My torches do not like others either. Fight or die depending on what touch.
I try to keep everything away from my scoly. except sometimes acans will get moved by them by crabs. No issues yet.
