Drunken Master Monk does a Disengage whenever they use Flurry of Blows, if you’re willing to look outside of those three.
Kensei is especially fun if the game allows guns.
Shadow has a ton of utility, and pass without trace is cool for a seal team.
4 Elements can be a lot of fun, but I recommend reducing all ki costs by 1, to a minimum of 1 ki. Makes it roughly 1/spell level, matching the cost of Shadow Monk Spells.
Also, Kensei/scout does allow you to be a sniper who can’t be pinned down, if that’s what you want. If you wanna stab without being pinned down, seriously look at Drunken Master, and remember that it doesn’t actually involve/require ACTUAL drunkenness.
Drunken Master might be interesting... maybe reflavor it to something like Art of Sea Legs or something similar! I might ask the DM to let me trade the proficiency with brewers supplies for proficiency with Carpenter's tools (for working on repairing the ship I'm assigned to.
