Since the standard E-6 1st developer is just a special B&W mix the Diafine news is no surprise.

What is interesting is that, instead of just skipping the reversal step you replaced the reversal step with fix and bleach.

Got lots of fix and I will have lots of bleach shortly.

A couple questions pop into my head.

Why bleach before the color develop?

Which color developer did you use? (C-41 or E-6)

That'd be a start.
I have played successfully with printing normal black and white films (Delta/HP-5) on RA-4 paper, the filter pack was thick but workable, so I'm not too worried about the orange mask. Using a piece of film as you suggest sounds workable too.
