Will i lose quality if i change sequence settings back to original size - (after having converted it to a lower resolution in a Multi Cam Sequence.)

A Cam has a resolution of 3200x1800, and B Cam has a resolution of 4608 x 2592.

I combined most of my library, over 50 different clips/takes into Multicam Sequences. What i didn't realize is i didn't input the frame size for the B Cam's resolution during the multi cam sequence creation, so all the sequences automatically converted to A Cam's frame size 3200x1800, cropping out part of my B Cam image.

What i want to know is if i go into the sequence settings of each sequence and edit the frame numbers to support B Cam's 4608 x 2592, will the resulting sequence be my original image, or will it be an upscaled image. Will there be any resolution loss? Or do i need to go back through my library and manually link all the appropriate clips & audio into new Multi Cam sequences.

Thank you kindly
