Maybe I don't understand the problem fully.
I'm on PC but I use a gamepad and crosshotbars for all battle actions. I play WAR, WHM, MNK, and BLM.
While I don't use more than 3 hotbars per job, each job can have a unique set of up to 8 bars. You can also choose if you want certain bars shared with all jobs or if you want to keep some independent.

Additionally you can set it to cycle through only specific bars when pressing R1, and you can split bars up to be used depending on whether your weapon is out or not. It can be set up to be very versatile.

One last note, although with regular hotbars you get 10 bars and only 8 with crosshotbars, the latter actually has more total slots since normal hotbars accommodate 12 abilities while each crosshotbar holds up to 16.
