I didn't know there was a rule against Toa wearing whatever mask they theoretically want. :P

Firstly, there is no plot hole with a Toa of Earth wearing a Mask of Flgiht. It can be considered a complication, yes, but it does not in any way contradict the lore. As mentioned before, it was an in-joke in the stories. Also, may I point out that your example of Takanuva (or any Toa, really) wearing the Kraakhan doesn't really work, since only Makuta can wear the Kraakhan. Whenever any non-Makuta so much as touches it, it shoots Shadow bolts at them, as we saw when Reidak picked it up.

As for the Kanohi Mohtrek (again), it was already established that Bitil had been calling became past versions of himself from Karda Nui. Plus, as mentioned before and as stated on BS01, the amount of duplicates summoned requires increased concentration. Makuta may have very advanced telepathic abilities, but even they have their limits. For any ordinary individual, summoning back more than five or six copies of themselves would most likely be strenuous, so imagine how much concentration it would require to summon more than a hundred versions. Bitil had already used his mask to summon back many versions of himself. In a single panel of the comics alone, he summoned seventeen versions of himself for one fight. Also, the Mohtrek is a very risk vs. reward sort've concept. Yes, you can swarm your enemies with countless versions of yourself, but you also dramatically increase your vulnerability at the same time. If an earlier version of yourself were to be killed, then the whole timeline would be rewritten. That is a pretty dangerous mask if you ask me. As such, Bitil would have to be cautious about how many versions he'd have to summon back, since he cannot control whether or not his past selves can be killed. This would explain why he only summons a relatively small number of his duplicates, rather than spamming himself into battle constantly.

This idea would also answer your question as to why Bitil never revolted against the Makuta. Makuta, as we already know, are enormously powerful individuals. We must not forget that they have access to powers like molecular disruption and teleportation. If Bitil were to lead an uprising against his fellow Makuta, regardless of how many versions he had, he would be faced with opponents who wield disintegration. Even if so much as one previous version of Bitil were to be killed, the present day version of Bitil would be killed, and therefore all other duplicates would disappear as well, since the version summoning them all no longer exists.
