[3.5] Marrulurk gestalt build brainstorm

[Dusk Eclipse]

Marrulurk are a monstrous humanoid found on Sandstorm (AKA It is hot outside)

For a mere 3d8 monstrous humanoid HD an LA +, you get various goodies

Natural Armor +2
STR +2 CON +4 DEX +6 INT+0 WIS +6 CHA +4
Death Attack
Sneak Attack
Poison Use
A nauseating breath weapon usable 1/day
Point Blank Shot and Rapid shot as Bonus feat
And a +4 racial bonus to hide and move silently check

Personally I believe they are quite good on normal play (Monstrous Humanoid is a decent HD, they can actually buy-off their LA right of the bat, there are "class" features" including one you need prestige class to get)

But I believe they will shine in gestalt, actually I thout of thi build for the gestalt arena
Swordsage 8/Blood claw Master 2/ Mot9 5// RHD 3/ LA +1/ Rogue 3/Warblade 2/Shadow Dancer 1/ template X

It ends with a respectable +5d6 (7d6 if using assassin's stance), the huge bonus to dex can be used to fuel Shadow Blade. small size helps for overal sneakines, poison use is circumstancial but MAY be useful, death attack..is meh but I like it anyway

Any way how does it looks like?

Bump and should I ditch shadowdancer and take other thing?
I considered spirit lion totem barbarian with whirling frenzy to add another attack, more damage (STR and DEX boost), pounce, and then maybe wildshape ranger going into master of the many forms?
