Have you tried using any of the footage from the DC that is available to stream?
I’ve heard it may’ve been an earlier edit of the DONNER CUT, with additional deleted material ( boy gets killed by Non, etc).
Oh yeah. I’m definitely using that to help, along with the Restored International Cut. I’m almost done with my edit of the first film, but I’ll need someone talented in VFX to help out to get the second film done.
