Yikes. I don't see that ever happening. The models are not employees of QVC, they work for modeling agencies as independent contractors. As such, they come & go, and set their schedules through their agency. That's why you can go very long periods of time between seeing Monica, or Jessica, for example.
Lots of the models have outside acting jobs, or other businesses that keep them busy when you don't see them on QVC.
Even if QVC wanted to do that, imagine the headache trying to keep up with updating the website on a daily basis for the comings and goings of the models. They barely update the hosts photos & profile pages more than once every 5 years.
By the way, there's one more new photo - Shawn's photo has been updated. They are apparently doing the updates one host at a time.
