I think that they are pretty well balanced now. Considering that they have the
Ranger keyword, it is fair enough that they each help each other (but not themselves, necessarily).
What if they had
ranger while you could spot a
ranger (or spot Aragorn) and then give them something else like a defender bonus for one and a damage bonus for the other if you can spot Elrond.
So it might look like:
Elohir's twilight cost is -2.
While you can spot a
ranger,
Elladan is a
ranger.
While you can spot Elrond,
Elladan is
defender +1.
And:
Elladan's twilight cost is -2.
While you can spot a
ranger, Elohir is a
ranger.
While you can spot Elrond, Elohir is
damage +1.
Not really what you had in mind with the original cards, but I kind of like the idea that they are team players and conform to what is around them.
