While those worlds certainly have some cool races, thematically they don't fit well within DDO. And a strong case could easily be made that Eberron has plenty of unique races from which to draw on before we start looking at other realms.

Kalashtar (they've already introduced the Dreaming Dark as well as psionic bonuses!) and Shifters are two prime examples.

Shifters, for example, could easily be implemented as enhancement path choices, similar to the Monk light/dark paths or the Cleric/Paladin/FvS weapon/god path choices (Sovereign Host, etc.). Further enhancements and feats could further improve these basic shifting abilities, and one need look no further than the Eberron sourcebook for some excellent examples of Shifter-feats (and Races of Eberron has some good ones too).
