It would be nice if mIRC could support all the possibilities of the API call SetWindowPos.
In particular, The ability to Move a window Off the screen. For example:
/window -pod @test 6000 6000 600 600
It is common practice to use /drawcopy with a hidden window to achieve some pseudo layering, or other effects. However, with an -h window you are always limited to the size of the mIRC client area, Or the screen resolution. An off screen window is better.
Also..
-h should work with desktop/ontop windows. As this is supported by the SetWindowPos API Call.

Yes a .DLL can do this. And i have a made a DLL to do so, However, i would rather this be part of the mIRC client, as it is very simple and fast to implement and has many uses to picture window coders.
