That's an interesting question. I have not tested the possibility but 
doubt that it will work.

The aif file derives its definitions from the OS-9 system call DWSET.
If your read the description of DWSET you will find the following styles 
for a window:
code     meaning
$FF      currently displayed screen
$00      process's current screen
$01      40x24      text
$02      80x24      text
$05      640x192x2  graphics
$06      320x192x4  graphics
$07      640x192x4  graphics
$08      320x192x16 graphics

There is no option here for a vdg window type and therefore the should 
not be in an aif file.

Again I've not tested this but I don't think you can run MultiVue from a 
vdg screen.
