Lange Coupler with two layer microstrip substrate in MWO

Hey,

Isn′t it possible to design a Lange Coupler in MWO with MLANGE AND LMAN on a two layer microstrip substrate(MSUB2)?
I already designed one on a one layer microstrip substrate(MSUB) but when i like to use MSUB2 i can change the reference in the MLANGE and LMAN.
Is there a solution? can anyone help me?

Kindest Regards,
Alex
