Any idea what the shape of the two hole solution might look like? I would like to explore putting it in the nose of my Ventus C

NASA has published several papers which are available on-line. The nose of a Ventus isn't too different from the probe shape.

Loek Boermans and a student of him created a pneumatic device which was yaw-free as well.
The title of the article is "Improvement of an Artificial Stall Warning System for Sailplanes", and it was presented in 2006 at the OSTIV congress in Eskilstuna, Sweden.

Most of these efforts focus on stall-warning, but for the most part AoA is rather linear with CL. You could calculate CL like so:

CL = (2* m * g)/(rho * v^2 * S)
m = mass in kg
g = gravitational constant in m/s^2 (9.81 approx)
S = wing surface in m^2
rho = air density in kg/m^3
v = true airspeed in m/s

You can also swap rho/v for rho0 (air density at sea level, roughly 1.225) and v_e (equivalent airspeed).
