In that case you are in luck.
You can probably define your own line discipline and then change the stack from

HCI <-> bt_ldisc <-> serial tty_driver

To this:

HCI <-> bt_ldisc <-> your (thin) driver <-> your_ldisc <-> serial tty_driver

The AXIS stack itself provides a good example of how to setup your own line
discipline, and btd.c shows how to assemble tty driver stacks.

Just one suggestion. The other, simpler, less portable way is to modify (make
your own) hci.c that can handle the extra bytes in the header.
