Prestressed wall panel

[JStructsteel]

Hi, I am designing a composite wall panel with 3 outside face, 3" insulation, and 4 inside face. The outside face has thin brick, 1.125" (not so thin in this case). Does anyone know of a problem prestressing the rest of that wythe(3"-1 1/8"=1 7/8" left) is there a minimum thickness required, needed, etc? I understand that bursting steel is required at the ends, and that could be alot in this case.
thanks
