the OP asked for an interesting build, yet has plenty of experience. dont take anyones advice (besides the one that really gave you a build like you asked) and just roll the character you want. a lot of good advice has been given even if it was negative as even negative info that is right is good info and better than false info that is positive...
you can still be a wf high ac paladin tank, and with 5 level ups in cha you can have a really high intim without multiclassing, and next patch paladins get intim as a class skill so that should really help. and since you wont be taking any thf or twf feats you get to play around with stuff like tower shield mastery, combat expertise, bastard sword proficiency etc... but if you go wf im sorry to say but you will have more than 400hp, most likely 450-500 range, if that is too much im sorry but wf are just not gimp in the hp department and it is hard to make one with gimp hp even if you try
ok joking aside you can make a fun build, but i def suggest intimidate as you rmain focus of aggro since your dps will be on the low side. beyond maxing cha you will want enough int to have 13 with a tome and plenty of dex while putting the rest in con, str wont matter in such a build as you wont be dpsing much.
and who knows, after all of this you may make something that is sought after so much in groups that people ask for your build so they can copy it!!!
