Hello
I have never tried that but can tell with 99% assurance this won't work. Why so? Converter supports only old versions of third party images which haven't been updated from quite a while. Even in the lucky circumstance PCS uses an understood file format, cloud environments pose additional requirements which won't be met by Converter.
As a workaround, you may try power on the machine and P2V it. Not supported either but worth a try.
