A large field of view is invaluable when star hopping and if this is all you are doing then does it really matter that you are losing some light? Don't worry too much about excessive exit pupils if general scanning of the sky is all you are doing. Yes the sky will be a ltlle more grey but stars are still there in high contrast.
A more important issue with low power eyepieces and fast 'scopes is that unless you get a highly corrected (more $) eyepiece you will get significant abberations off axis; a common one being astigmatism but also field curvature. If the edge of field is not sharp then having a wide field eyepiece is of no benefit. If stars are out of focus, imagine what a galaxy looks like (invisible).
Note too if you use a Paracorr your exit pupil is reduced by 15% and many abberations are corrected especially coma which is from the primary optics (paraboloidal mirror).
