Barbarian / Monk mix

[Archmic]

So I've been playing around with an idea.
A monk/barbarian mix char.
If you take the martial artist arch type you can be any alignment you want then mix it with the brutal pugalist arch type and it sounds really fun.
There is a recommended rage power that I have a view point on though: Brawler.

For those not familiar with it the brawler rage power upgrades the barbarian's unarmed strike to 1d6; if he already has improved unarmed strike; or gives him the imrpoved unarmed strike feat; if he doesnt have the feat. Both of these effects only happen while raging.

In essence it upgrades his unarmed strike one step. It makes sense to me then that if he already has an unarmed strike damage of say 1d10; from his monk levels; and he takes this rage power his unarmed strike damage should upgrade one step while raging to 2d6.

Any thoughts on this or the build?
I like the tHoughton of the build because you can cross class two classes that were never compatible before; unless you were playing oriental adventures but even then the restrictions were hard to make a fun char with.

The brawler rage power pegs the unarmed strike damage at 1d6 if she already has the Improved Unarmed Strike feat. The rage power does not say that unarmed strike damage is increased by one step. In my view, the monk's unarmed strike damage will supersede the brawler rage power, not stack with it.

You can also mix Bloodrager with Monk without worrying about alignment.

Also, Brawler does not increase it by one step. It gives you a d6. Pink Dragon is correct
