Monk intimitank maximum DR possible?

[wax_on_wax_off]

So I was thinking about making a tank build but not sure what how viable monk is for the qualities that I wish to have in a tank.

Maximum DR a monk can get:
10 epic as base (or 8/- grandmaster of earth)

+

10 = (15 bab + 5 DP clickies)/2
3 grandmaster of earth
= 23/epic or 21/-
No room for two weapon blocking

Human is the only choice to get intimidate up high enough to be workable in most situations.

32 point build.
Str 16 = 14 + 2 tome
Dex 17 = 15 + 2 tome
Con 21 = 14 + 5 levels + 2 tome
Int 10 = 8 + 2 tome
Wis 16 = 14 + 2 tome
cha 16 = 14 +2 tome

7 base feats:improved two weapon fighting, greater two weapon fighting, least dragonmark of sentinel, lesser dragonmark of sentinel, greater dragonmark of sentinel, cleave (Shintao prereq), improved critical: bludgeoning
3 bonus monk feats: toughness, power attack, two weapon fighting
1 human bonus feat: skill focus: intimidate

There would be quite a few options on how to play. Earth stance for max blocking DR and maximum HP and ki generation while being hit. Fire stance for positive healing amp (with bracers). Water stance for high stunning fist DCs.

Edit: swapped build around a bit. No room for CE if taking full intimidate lines. Likely not enough room to take all desired enhancements.
