 Yes, absolutely !
 Off hand, I can think of a few ways, none of them cheap.
 Now, if cost is a concern, I'll back off of that statement.

 I may disagree with that one, again based on the cost condition above.

 That would certainly work, and I think so would a ring diplexer.
 In fact, the closer in frequency, the better the ring works.
 A bit of real engineering would be called for.
