Sonic Incision
If you use HP filter on OH tracks at like ~500-600 Hz, except for some artifacts (that will probably not be audible in a full mix), there shouldn't be any major problems. What you are trying to do is basically the same as just editing the kick and the rest of the kit separately, and than just using edited kick to feed the trigger plugin, which is, I dare to say, a common practice today, especially with all those 'technical' drummers we all have the honour to listen, record and edit.
