Do it the other way around for a better time. Take your roll(s) first. Oxy is great for coming down, but taking it before rolling not only conflicts with the energy from a good pill, but is also a bit harder on your heart.
The actual danger from a low dose during your roll is probably very small, and I am not sure if anyone has actually quantified it beyond 'no uppers and downers at the same time'. I have in fact tried exactly what you are proposing, and I now use oxy after rather than before.
The absolute best time for your first dose of oxy is when you are certain you are down and you are just barely starting to crash.
Oxy right at that point is better than the first roll, in fact. Save it for after--you will be glad you did, believe me.
