Oh, thaaaaaat...

But it is so dull :(

I've got some kind of compilation based on those variants and a few more from some Dragon Magazine issues.
For example, this one is from it.

There is also a hunting monk, a holy monk, martial monk, raging monk(lol), sidewinder monk, steadfast monk, vigilant monk, wild monk.

And a couple extra 'styles':

Skill Focus(any Strength-based
–or– Dexterity-based skill).
You may ‘Take 10’ on any Strength-based or Dexterity-
based skill check, even if distraction would normally not all
you to do so.

Wing Chun Kuen (aware of his/her surroundings and how to use them)

When you enter combat and are not surprised, gain your
Wisdom modifier (if any) as a bonus to your Initiative
check.

Wushu (smart tacticians who attack in unexpected directions)

Show
Skill Bonus: Tumble
1st
lvl Feat: Improved Initiative
2nd
lvl Feat: Power Attack
6th
lvl Feat: Improved Feint
Bluff: 4 ranks.
Sense Motive: 9 ranks.
When you make a Bluff check in order to Feint in combat,
gain ˝ Monk levels as a bonus.


Plus 5 martial arts schools as boring and random. Basically, there are some Ability and feat prerequisites, you gain a small bonus for qualifying for them.
Then the 1st level mastery + higher ability, feat and skill ranks to qualify for a bit better bonus.
