I’m doing a similar thing with my duelist, but I call them Regimens (might change to techniques), and you know more than you have prepared for the day, more like the artificer’s infusions.Pretty much said any capstone not equal to Cleric's souped up Wish it's not a worth our time.
Also suggested monks should get invocations like the warlock, call them Stances and raid 3.5's Tome of Battle for ideas.
The idea being you have to ready yourself and perform ritual preparations in order to focus on specific techniques, like the ability to create blades and balls of air when you strike, extending your reach with weapons and unarmed strikes, or performing very fast and deadly charge attacks, or fighting acrobatically, or gaining a riposte any time someone misses you while they have disadvantage, etc.
