USD Instancer point to Niagara

Hey

Would it be possible to get USD Instance points to Niagara?
Been importing cool sims with 30.000 points with sphere instances/ animations on it
working but only at 6-8 FPS. Could or would there be some other workflow
allowing for more? In USD composer I can run millions and Notch 30 mil

So why not in UE?

Thanks
