Is it possable to connect 2 MFM/RLL/ESDI controllers under Unix?

Under AT&T Unix 3.2 there are tantalizing allusions to the ability to
handle multiple controllers.  For example, the diskadd and disksetup
programs accept a "controller" specification on their command lines.
I would like to connect a DPT RLL controller and a second [MFM/RLL/ESDI]
controller in the same system running AT&T 3.2 (or later :-)
Has anyone done this?  Have you tried and failed?  If so, email me.

I will post a summary, so please don't send "me-too" messages because
I will ignore them :-)
