As said, Mooncancer is specific to Moon Cell A.I went rogue so not only BB, every Servant affiliated with Moon Cell may got Mooncancer version; as TM announced second Extella games is on progress, its possible that Mooncancer and Alter Ego will got new members so it won't limited to Sakurafaces.

Archimedes naturally a Caster but he can be a Mooncancer if scenario said so. I can see him among Mooncancer boss though simply because DW and TM didn't want him to be easily one-shot by J. Alter as he's the one responsible to Moon Cell security.
