Scythe or Hell Revealed on Nightmare! Possible?

Like seriously, has anyone completed any of these WADs on NM? I can barely finish these on Hurt Me Plenty! 

Doesn't look like it -- there's nothing in DSDA, anyway.

EDIT: Just to be clear: Yes, it is possible, but it's never been done as far as I can tell.

It should be possible.

Anything's possible for the speedrunners.

There's NM100 demos and even a NM-Speed playlist on the DSDA Youtube for Scythe.  So yep, possible and documented.

Hell Revealed perhaps not. Even assuming you found a way past map07, then the start of map18 looks like an impossible barrier.
