Can You Be Pro Drop and Still Have OSV or OVS?

I thought he was going to choose between the two, like how do I have them active as that? He just hasn't decided yet. His main issue is whether you can have an object subject language that is pro drop and still be OSV or OVS. My suspicion is OVS will be a little bit easier to think about and learn because you have one thing that's before the verb,. If you don't have case marking, then do whatever you want. The own, if you're going to have OSV and you are not doing case marking, there might be some potential confusions.
