I think two wiims, of either / both varients, would do what you want - isn't that the point of being able to group them?!
What receiver is attached to the turntable?
Does the denon avr in the other room have heos?
i.e. an alternative solution might be using a heos ecosystem, such as connecting the TT to a heos (denon) link or other cheap denon/marantz amp with heos.
But two new wiims might be as cheap / cheaper than even a 2nd hand heos solution.
Edit: I don't have two wiims (yet), but do have a heos link and a marantz avr with heos.
Just plugged my phone into the link's line in, grouped the two heos "rooms", and the avr played the same song, as expected. A quick fiddle with audio delay settings in the heos app and it was as close as needed to synchronised.
I've seen that the wiims have audio delay capabilities too, but as I only have one I can't comment on it.
As for doing your vinyl playback a disservice... I'm sure you'll still be able to hear the snap, crackle and pop in the other room
