Used Dynaudio's Confidence(I think this is right) use the world class Dynaudio Esotar 330 tweeter(same as Confidence, Sonus Faber Extrema's, etc). I'm not sure if those Dyn's are ported or what not. You might do best with acoustic suspension(sealed) designs that might do better closer to the boundaries. OTherwise you could consider smaller sealed monitors with a sub(s). Often small sealed monitors do better closer to walls. Still, that might be tough ultimately.
Used What Puppies will need to be out in the room. There are lots of high end speakers you might find that you like in that price however. Avantgard Uno's can be had at the $5k used range, and you can adjust the powered woofers somewhat to try to balance out your sound if you've got to get em closer to the walls and such. Infact, you'll probably not be able to beat these speakers for your applications(although off axis isn't possible with these speakers).
Another suggestion would be for you to biamp a pair of high end speakers you like, and put a parametric EQ on the woofers!!!! You'll otherwise be asking for lumpy, boomy, uneven bass next to the walls usually(depending of course).
Active speakers where you can get some more bass flexibility options will work for you, if you can find the right speakers.
If I can think of anything else pressently, I'll let you know
