In editor anamorphic effects

Trying to simulate in editor anamorphic look for a green screen workflow.
Have gone thru William Faucher’s excellent tutorial

but it still requires you to render out to MRQ in order to get your ‘de-squeezed’ image.

Is there any way to accomplish this in editor and or PIE without rendering out?
ie some combination of 2:39:1 format + oval bokeh + horizontal bloom/flare effects.
