I drop weights all the time, but then RHIP.
And yes, that is how the eccentric is eliminated in the OL's. Try to carefully lower a one rep max snatch. And let me know where to send flowers.
I would just perform singles, or maybe something along the lines of a lower intensity dynamic effort day. To eliminate the negative, basically free fall with the weight, which is why it has to be light. Slowly increase the speed at which you plummet, because if you are not used to this, you can get hurt. Badly.
If you are squatting in a ballistic manner, this is a pretty good time to stretch (afterwards, of course).
