I've done it and found nothing too fatiguing about it though I didn't get too heavy and didn't go too high in my reps either. All I did was sub my warmup for squats as overhead squats and kept the weight the same. For example:
My warmup for squats is typically: 45 x 5, 95 x 4, 135 x 3, 185 x 2, 225 x 1 and then singles up until my working weight.
When I subbed in OHS I did it like this:
OHS - stick x 10, 45 x 5, 95 x 4, 135 x 3
BS - 185 x 2....etc
