I like the Diehard feat but if you gave that feat up or took it later you could use any race.

My question is this, if you had this as a base platform for your first 6 levels, where would you go from there? Alignment will be restricted to Lawful Good or Lawful Neutral by the Monk levels. Minimum required abilities is 13 for STR, DEX, and INT to obtain the feats, beyond that use whatever you like for starting abilities...

if you were WF you wouldnt need diehard :p

You could consider going 6 levels of ranger, 4 more fighter. This would give you tempest and enough feats to be a full fledged 2 weapon fighter with all the goodies to go with it.
