So there is a gap between my case and the desk i have it sitting on and I'm wondering if I could perhaps squeze and internal fan there

In the following photo you see the gap between the ground and my case (acrylic) with a bottle cap in the shot for the sake of size comparison.

The idea is mostly to provide my GPU with some better air evac than just my side mounted 80mm.

Not worth putting a fan with that little space. If you need more air to move towards your GPU, you're better off pointing some 120mm fans directly into it. Also make sure that you have sufficient air flow inside the whole case.

Air goes where it is forced. The airflow won't be GREAT, but a fan wouldn't hurt.

Air goes where it can. Forcing helps but if there is nowhere for it to go it won't.

Raise your case up with some blocks under the feet. I always raise my cases to have 40+mm clearance for bottom fans. Area of fan should have as much or more intake area.. circumference * clearance.

80mm fan area = 20mm clearance.
120mm fan area = 30mm clearance
140mm fan area = 35mm clearance

It would certainly not hurt, but I would definitely get a fan filter for it as its close enough to where it will actively collect dust.

Something like a Corsair SP120 PE, Cougar (don't know their model names), Scythe Kama2, Silverstone FM123/FN123 (the one that has a lot of static pressure), or surprisingly enough, the Rosewill Hyperborea or the red one with the wire grill. Any of those, or anything similar (more than60CFM and a mminimum of 2.2mmH2O) would be ideal, as the fan grill + filter provide significant resistance.
