I reaaally doubt such a character being Lawful.
It's sort of like the relationship between squares and rectangles; just as all squares are rectangles but not all rectangles are squares, all characters who make important choices by rolling for it are chaotic, but not all chaotic characters will roll dice to make important choices.
Um...60 hp for a feat seems pretty powerful, to the point of "Why would anyone not take this?" it'd on its own more than double any wiz/sor's hitpoints. The Improved Toughness feat is +1hp/L, requires +2 base Fortsave.
Keep in mind that I am using RoW scaling feats and those +3 hp per level is being balanced stuff like:
You are just as dangerous to everyone around you as to anyone around you.
Benefits: As a full round action, you may make a single attack against each opponent you can reach. Roll one attack roll and compare to each available opponent's AC individually.
+1: You gain a +3 bonus to Balance checks.
+6: As a full round action, you may take a regular move action and make a single attack against each opponent you can reach at any point during your movement. Roll one attack roll and compare to each available opponent's AC individually.
+11: Until your next round after making a whirlwind attack, you may take an attack of opportunity against any opponent that enters your threatened area.
+16: As a full round action, you take a charge action, overrunning any creature in your path, and may make a single attack against each opponent you can reach at any point during your movement. Roll one attack roll and compare to each available opponent's AC individually.
or
You kill really large numbers of people.
Benefits: You gain a number of extra attacks of opportunity each round equal to your Dexterity Bonus (if positive).
+1: Whenever you drop an opponent with a melee attack, you are entitled to a bonus "cleave" attack against another opponent you threaten. You may not take a 5' step or otherwise move before taking this bonus attack. This Cleave attack is considered an attack of opportunity.
+6: You may take a bonus 5' step every time you are entitled to a Cleave attack, which you may take either before or after the attack.
+11: You may generate an aura of fear on any opponents within 10' of yourself whenever you drop an opponent in melee. The save DC is 10 + the Hit Dice of the dropped creature.
+16: Opponents you have the Edge against provoke an attack of opportunity from you by moving into your threatened area or attacking you.
If I were making a character, I'd want to roll instead, really. Here are your random numbers:
6 1 4 2
6 4 1 4
6 6 6 1
5 2 5 2
6 4 6 6
6 6 4 5

which would be 18/18/17/14/12/12
and I'd ask if crafting in the background is acceptable, whether traits/flaws are allowed...
Elite array is balanced with 3d6 with no rerolls, not 4d6, keep 3. So, according to those rolls your stats would be 18/16/16/12/11/11.
Assuming you are not managing to horribly screw yourself over/break the rules in half, crafting is fine. Traits/flaws would probabily be handed with the backgrounds mechanic from RoW, but honestly, as long as they are of similar scale to a background, then you could take a set of traits/flaws.
and setting-specifically whether dwarves are too hated by locals to be allowed in goblin hacienda.
No worse off than an orc in a human town. The main issue is that there is already a party member who hates dwarves.
