Not without some pretty radical surgery, no. Mutter would need a huge rework to
be a WM across multiple X servers at the same time, as would the XWayland
integration (e.g. to cope with XIDs no longer being unique).

There's also an additional complication that GTK+2 is HiDPI but not mixed-DPI
aware; it seems to just pick a scaling factor from the overall logical display
dimensions, so will always scale up to HiDPI, even if it's currently positioned
on a low-DPI display. (The silver lining in that cloud is that GTK+2 or Chrome,
whichever, don't actually listen to updates on the scaling-factor GSetting, so
you can hack around it by changing the GSetting, launching, then changing it
back ...)
