This video is the evidence I have that it will work in reverse, hence I feel comfortable (sort of);

Pushing the Envelope - Backward Naca Ducts

Plus, as it happens I have been lucky enough to source a bonnet which I can cut my "maiden" hole in.

For it to work, the air pressure on the outside will need to be lower than on the inside. With the profile of the bonnet widening by the duct and the blockage of the windscreen in the flow, there may be an increase in pressure on the outside of the bonnet in the duct area, unless the vortices from the edge of the windscreen have a scavenge effect in reducing the pressure in the area near the duct, as well as the area behind the windscreen.

Thank you Tom and Simon.
Whilst Im wanting to let "function" rule over "form" - admittedly the "vanity" element makes for a nice bonus Nerd

Thank you James - you clearly know a lot more about aerodynamics than I do.
Perhaps its wishful thinking - but either way I'd like to think that my objective of getting air flow to the pedal area will be achieved

Having created a hole, the irony is I now need to fill it. 
For this I've turned to CAD (both the Cardboard and Computer Aided Design variety). 
Here's the work in progress laptop CAD

I've scrapped the idea of using 3D printed plastic, due to the firewall requirement, instead opting for 2mm sheet.
