The Royal omelette (NQ) is actually almost identical to the Imperial (HQ), the 3 differences being duration (3 vs 4 hours) and the Attack caps are 5 higher on the HQ (80 vs 85). For the purposes of the setup I posted, the NQ is perfectly viable - I just preferred the final rounded Attack figure. 
If you had 5/5 Dex merits then you'd be looking at a very tempting setup (affordability/attainability), you could just swap out:
Ancient torque > Peacock charm/amulet
Cuchulain's mantle > Commander's cape
This would keep your Dex at +60, but you'd have to be willing to take the net loss of 4 Acc in the process (+38 as opposed to +42 in my example setup).
