I get the feeling of not wanting to follow the same cookie cutter plan as everyone else, but Phoenix and JKR are both important squads you'll want to get done right away. Especially Phoenix - they aren't very useful in the late game, so it's best to get them strong enough for Thrawn/EP now while you can still get some use out of them. Fortunately you don't need to get them super geared - g9 should be enough.
Shooting straight for Darth Revan after JKR might be a bit over-ambitious. DR teams need two things to shine: Darth Malak and LOT of speed, which you likely don't have the mods for yet. The light side half of Malak's event will also be brutally difficult with early-game mods, unless you've had absolutely insane luck farming them.
Honestly I'd probably just focus on getting those done and then see what's what. By then at least one of the new Galactic Legends will probably be available, so that might end up being the fastest way to the top of the arena.
