The 2 cube dice are glued on 1 of their faces
to make a 1 x 1 x 2 die w/ new configurations.
Any 2 of its sides now can add to:       
5, 6, 7, 8, 9, 20,11,12,13,14,15,16
       __________ __________
     /                 /                  /\

 /__________ /_________ /       \   
 \                  \                 \       /
   \                 \                 \    /
    \__________\__________\/

Just so that I'm sure of what you mean. When you say that any two of the sides can be used to form those sums, are you referring to this die as having 6 sides--4 of them have two faces, and 2 of them have just one face?

I don't see how you can achive this set of 2-side totals with 2 standard dice.

If we can add any 2 sides there should be 6C2 = 15 totals. Whereas, OP lists just 12. If we only add each 2 adjacent sides, then we get a set of 12 2-side totals.

However, I don't see how that set of 2-side totals is possible with standard dice.
