Will this circuit work as I plan? 4 input SE audio switcher with connected input grounds.

Here's what I've got. I'm mostly worried about the ground from all inputs connecting together. Is that going to cause any problems?
Otherwise, I'm not 100% on whether or not I've connected the volume pots correctly, and if there will be audible SQ problems from using a single relay per input, rather than per channel.
Hopefully my schematic is legible, I don't have experience with this.
