I've built a similar monk based on your post here and am having a lot of fun with it. Since I don't have anything to reincarnate I am leveling him up and just did Thids at level 48 last night. I was able to stun most everything, though was disappointed to discover that the WWA stun attack is useless. (Anything that could be affected would be killed faster just by hitting it.)
I made some adjustments due to the fact that I have no pandects or artifacts to use. I changed the DEX and WIS starting values to 20 after subrace mods (8 pts each) and used the extra 2 points to bump up the STR. I'm thinking now that I may have been better off putting them into CON. Then I swapped 2 of the WIS bumps to DEX. I also added in a ranger level and 2 fighter levels in epic levels for the bonus feats. Fighters get Improved Stunning Fist as a bonus feat for some reason. The ranger level got me EWF: Unarmed. I also used Strong Soul, Legendary Soul, and Great Fortitude to get my saves to a projected 67w, 62f, 70r.
Naked at level 60, he should reach 44 DEX and 26 WIS and hit the 70 DC max on Stunning Fist. This gives him +14 enhancement on his gloves when geared, with room to grow if/when I get +14 gear and/or demi status.
