Be careful about the terms "inbound" and "outbound" here... "Inbound" to the holding fix/IAF is "outbound" on FQG R037.
This is an unusual approach profile. However, once cleared for the approach, I would decelerate to 205 KIAS and configure as necessary in the holding pattern, descending to MHA of 1500M/5910' until inbound to the IAF (outbound, within 1/2 scale deflection of the FQG R037). I would then descend to reach D20 at 1500M/4930' and continue the descent to reach D28 at 800M/2630'.
That way, I would comply with any confusing or possibly conflicting restrictions.
