External Meter Bridge (my solution)

So, I would really like a pair of physical Dorrough meters. I was thinking I'd feed them with a pair of outs separate from my monitors, so they would not be affected by the volume knob on my Apollo. However, we're talking like $300 to pick up a pair used.
 
So I got to thinking...
 
I love Waves Dorrough meters, so I just ordered this:
 
https://www.amazon.com/gp/product/B01E9ZPOE8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
 
It's an 8" monitor for about $67. My plan is to put the Waves Dorrough from the master bus on this dedicated monitor and use it as an external meter bridge.
 
Brilliant or stupid?
