AFAIK, no, that's not possible, as it's xorg that handles screen 
resolution, and nobody has (yet) hooked up virtual desktop switching to 
the xorg screen resolution mechanism.

It is, however, possible to change resolutions with a single command, 
xrandr, followed by the output you want to switch, the resolution, etc, on 
the command line, and given that, to create a script that simplifies 
things.  I've done that here.

And it is possible to hook either the individual commands or the script up 
to specific keyboard shortcuts, as it's possible to do with any command.

At that point, it's a simple matter of hitting the hotkey sequence, and 
the resolution changes according to what the linked command invoked.  I've 
done that here as well, with a whole series of hotkeys setup, to switch to 
any one of a whole set of screen resolution combinations (combinations, as 
I have dual monitors).

In theory, then, you could setup a script that would change both the 
screen resolution and the virtual desktop, thus linking the concepts, but 
to my knowledge, no one has done so (yet?).  And in practice, I'd guess 
that the need for such a thing is narrow enough that it's not likely to be 
implemented as a mass-market thing anyway.  More likely, individual 
installations would hack a script together to do what they need, which is 
really what I've done here with my scripts, even though what I wanted (and 
implemented) wasn't exactly what you describe.

That's a rather high level discussion.  If you want a bit more detail, we 
can discuss things further.  FWIW, I've used a combination of bash 
scripting, xrander invocation, and khotkey triggering, for my own solution.

If you are interested, include some details like how many monitors you use 
and their relationship to each other, the resolutions your interested in, 
whether you know much about bash scripting so I know how much explanation 
I have to do, etc, and perhaps together, we can come up with at least the 
hotkey invoked resolution switching.  I know that much works as I do it 
here.  Hooking that into virtual desktop switching may be a bit more 
challenging, but we'll see.
