Since it's 3053, Tuk has taken place & Comstar's army is no longer secret. Sure, more than a couple CS mechs are exclusive but there are mechs like the Mauler, for example, that are exclusive to certain factions, Kurita in this case. I don't see why we shouldn't consider Comstar mechs.
For a list of CS clan invasion era mechs follow this link:

Some of these went extinct from the rest of the IS, I'm mainly talking about those.
