- Chakotay would be a more mysterious character with his character being unfurled as the first season goes on. A former Senior Fleet Officer (a 1 Pip Admiral or a Fleet Captain) sent to infiltrate the Maquis but went native, becoming more a "man of the people" stateman leader of the Maquis with only his closest allies knowing the truth about who he was. He used his Fleeter training (and connections with Starfleet Intelligence) to acquire better weapons and materials for his group to use. But he also made sure not to do anything to tip Starfleet off to his true defection so he made sure to focus mainly on fighting Cardassians while avoiding Starfleet confrontations as much as possible.
This expert “double-triple agent” performance was why he was able to maintain his Access Codes to Starfleet systems. But it didn’t go unnoticed which is why he had Tuvok sent in to “evaluate” him. His style of command is at its core still Fleeter but tempered with decades of experience and knowing what its’ like to be cut off from higher command and having to fend for yourself (having been put in these situations plenty of times during his career by idiot admirals). This would contrast with Janeway and Tuvoks’ command style, which is dependent upon the chain of command, being very military in structure and practice.
But rather than be immediate adversaries, I'd actually have Chakotay have no problem with Janeway as a person as he can see how a Science Officer becoming the Captain would stress a person. Plus he's ex-fleet himself so I'd think out of all the Maquis he would be the first to realize the necessity of working together to survive, and as such he would face insubordination and distrust from some of his own for being a "sell-out" much like the more open-voiced Fleeters would voice their concerns about a "lab rat" like Janeway being their Leader. Thus the conflict would be Chakotay and Janeway against their own groups.
Tuvok would be Chakotay’s true nemesis at first, both clashing with the other for the position as Janeway’s Adviser. This gets resolved when she asserts herself as Captain and both accept this. Thus, while still allies of convenience their main reason for opposing the other is not an issue anymore so they have less reason to keep it up.
Actor preferably someone in their late 50s or early 60s, old enough to be Janeway’s father.
