CX-90 vs. CX-9 Roof Rails

Hi, has anyone tried fitting an aftermarket (Thule, Yakima, etc.) roof rack from a CX-9 on the CX-90? No companies have the CX-90 listed yet and I'm wondering if I can just go by the CX-9 fitment. Thanks.
My 8yr old Thule (big black box) connects securely to the new factory cross bars on my CX-90. I just drove across the country with it and had no issues.
