Goal: 12 maneuvers readied for Crusader, 10 maneuvers granted, but only 10 maneuvers known!
You cannot ready all of your maneuvers, so you get into areas that the rules don't cover. Most likely, you just get into the situation where you have 10 granted maneuvers and nothing left to grant, so your maneuvers refresh themselves every single round.
This situation is induced by adding extra maneuvers known from PrCs to one martial adept progression, and adding the maneuvers readied to another progression. The rules on page 96 state that you can choose which class you add new maneuvers and extra readied to, but each entry is listed independently of the other and has nothing stating that it has to be the same class. So the new maneuvers known are (mostly) added to the Warblade and Swordsage progressions, while all 7 extra maneuvers readied (and consequently granted) are added to Crusader.
The end result should be that you have 2 9th level maneuvers, 3 8th level maneuvers, and 5 5th level maneuvers available to you each round, plus whatever you pick up for the Warblade and Swordsage sides.
Build Notes: The use of a late level of Crusader and early levels of Shadow Sun Ninja was inspired by the various Reshar/all 9th level maneuver builds. The sole Eternal Blade level in there for the 1/day Eternal Training. My initial reading of the ability made me think it might increase your maneuvers granted when you use it, and not just for the immediate granting. Now I'm not so sure. It can safely be replaced by another level of anything, really, which also frees up the race. Similarly, the exact order of the Blooclaw Master and Shadowsun Ninja levels can be modified. They are just there for improved initiator level for Crusader, and for the extra readied maneuvers that they grant at 3rd/5th, just after taking the Crusader level.
The rules for this are shaky, I'll admit, but what is actually there seems to support this idea. Please point out any flaws or rules I may have missed. This build is not perfectly optimized, it's only a rough skeleton to prove the concept.
Edit: Fixed an error in the level stub. It had SSN 8 instead of SSN 5/BlcM 3
