Hi Aidan,
Oversampling by itself is not a problem, it just means longer sub-exposures to get past the read noise, and less FOV for the same resolution, the actual SNR is not affected. If you can live with these, and your camera can control the dark current for the longer subs, then by all means oversample.
BTW a 'benefit" of oversampling is that you could be less prone to saturating/blooming
(sorta, getting past the read noise might put you back to square one in terms of saturating, one would have to do the math)
Best,
