Yes, Lightroom has no effect on PSE or your PSE Organizer.
I really like the PSE Organizer and may want to stay with it after trying Lightroom and Creative Cloud.
My opinion is that this is not a good idea. The PSE Organizer is not designed to work with Lightroom and so it does not work well with Lightroom, and you will be making your life difficult by staying with the PSE Organizer and using Lightroom. A better idea is to do all photo management and initial photo editing in Lightroom, and then use the PSE editor for additional editing power, such capability was designed into Lightroom and works very smoothly.
