Still have about 1/3 oil reservoir tank left of this oil.
Silly question, and think I know the answer, but have to ask......
Could I possibly mix XD50 synthetic with the XD30 'non synthetic' ?
Otherwise will wait to oil is almost completely exhausted before swapping out.
Thanks,

You can mix them with no issues. If it still smokes too much at idle, you'll probably want to address the oil injection pump. That said, I can't fathom how it would possibly add too much oil, it operates directly on engine intake pulses (so it can't possibly run too fast) and is a positive displacement pump, if memory serves. I suppose it might have a failed part inside, but I dunno
The only failure I am aware of with them is when they stop pumping and you replace them. AFAIK, there are no rebuild kits for the oil side of the pump.
Here's a cutaway diagram of the VRO pump like you have:
