Maybe Arlon, Taconic or Rogers can help you. We buy organic boards with thin to heavy aluminium or brass backsides. They should know about handling mismatching etc. Don't know about their multilayer capacity. Our largest brass backside boards are wide like a 14" TV screen and they seem to work despite the theoretical mismatch. All is a question of material balance of course....

Subject: [TN] aluminum bonded PCB


I am looking for information on a circuit board house that can supply a
multilayer PCB bonded to a thin aluminum sheet(heatsinking purposes).  If
you know of a supplier or if you are doing this process, please contact me,
I need to learn about this process and who can supply a board ready for
populating.

Thanks
