The usual meters out there estimate the film plane light intensity using an equation (too difficult to type here) that takes into account the following:
b = Constant with units of lx⋅cd–1⋅m2
θ = Angle between subject and lens axis
N = Relative aperture (fnumber) of lens
F = Lens flare correction factor
f = Focal length of lens in m
V = Lens vignetting factor
Ls = Luminance of subject in cd⋅m–2
T = Lens transmittance factor
u = Subject distance in m
So, yes you could solve the equation for the above variables then predict the exposure.
Much easier to just do some test strips.
