Definitely not realistic or fair. Delmon Young has about zero trade value, and Adam Lind doesn't have much more than that. If you only want to give those guys up, and want it to be fair, you'd have to set your sights a lot lower than Carlos Beltran. For Beltran, you'd have to offer different players like Rasmus and a 5-star potential fake minor league pitcher might work. Remember STL is an NL team and has no use for DH types like Adam Lind.
