One thing you could do (and I would recommenced this if it is feasible) would be to calculate direct lighting dynamically (that way you could use a Oren-Nayar BRDF) and then for indirect lighting, use low resolution light maps that contain indirect light only. Alternatively you could use directional light maps or something like H-basis coefficients to get better indirect lighting. My intuition is that for the indirect light, Oren-Nayar wouldn't make too big of a difference.
