Which shell formulation (ELFORM in *SECTION_SHELL) are you using? If it's plane strain (shell ELFORM=13), you can instead model a single layer of 3D solid elements with nodal constraints in the thickness direction. There should then be no perceived restrictions on how you orient your orthotropic material directions. Apologies if I've misunderstood your situation.
