What's wrong with simply letting you pick one target for Elusive Target, even if you don't have to pick one because of use of a Dodge variant. Why make Elusive Target less useful?
This is what we do as in our groups' games, Dodge is house ruled to be +1 to AC from everybody, so when a feat using Dodge as a prereq comes up, then you pick a target for its effects if it orginally depended on Dodge's choice of target.
Note there is also a Psionic Dodge feat (CPsi IIRC,) that works as a replacement for Dodge like some of the above.
