I guess that should be possible.

I don't know the internals of plasma-desktop but I guess it could quite easy 
be extended to take an optional argument which holds the containment it should 
be responsible for.
So launching it without arguments would make it handle all configured 
containments but launching several instances with arguments would make each 
instance just handle one.

Would need a slighlty different approach for any kind of D-Bus interaction (if 
some programs are using that) since only one program can hold the D-Bus name 

Might be worthwhile to experiment whether plasmamoidviewer could be used to 
run just a panel.
I.e. running plasma-desktop just as the desktop and running plasmoidviewer as 
the panel process.
