You can convert from an 8-bit jpeg to a 16-bit tiff (or other 16-bit capable format). But it doesn't really help with your image quality or post processing malleability. Photoshop uses a pretty straightforward linear scaling to go from 8-bit up to its 16-bit format and back to 8-bit so you're not going to get any benefit from converting back and forth between the two during your processing .
You could convert to 16-bits if you had some 8-bit images that you wanted to merge with 16-bit images while maintaining the full data set of the latter files. Or if there are tools that only work on 16-bit images that you want to use. But there's no creating the missing information.
