The steam instruments are in the standard T positions but the centre 2 slots
where the AI and DI normall go are vacant.
I would use the ASI and ALT as primary instruments - much quicker to set the
ALT between QFE and QNH with a knob than playing with buttons. The ASI being
analogue is much easier to glance at and get an idea if you are fast or
slow. Trends are much easier to see on analogue instruments too.
The ASI / Alt features on the Dynon would indeed be a backup to these steam
instruments (if used at all) - the Dynon would be the primary attitude
indicator (other than the turn coordinator) and the primary DI (backed up by
the compas and skymap GPS).
As there is no statutory requirement for a DI / AH and the aircraft has the
mandatory instruments (and more), personally I can't see why the PFA would
object but, I've not been through the exercise (yet)
