Bombnuke To answer your question No. Any appliance that uses a disposable tank is "Hi Pressure" your rig's system at the quick disconnect is low pressure (11" wc/6.35 oz) The "control" on the grill is the regulator if you can find an OEM conversion to low pressure it would work otherwise you will have an extremely low flame prone to blow out. I was in CW and saw Oylmpian grill that could be converted. To use yours you would need to connect between the bottle and the rig's regulator with one of the "extenda" type hoses and fittings, that would get you the pressure you need.
Hope this helps
