Also, is anyone interested in helping IVTC the median-of-five video?

Can the image even be properly IVTC'ed? The problem is that this was done on the older kind of telecine which used pickup tubes. ... from watching old transfers like these, it seems like even if you were to pull the fields apart, they'd still contain the picture info from adjacent frames smeared together.

Actually, that is what happened with those kinds of telecines. I've noticed the very same effect when examining DVD releases of the 1950's science fiction television series "Rocky Jones, Space Ranger" http://www.oldies.com/collection-view/Rocky-Jones-Space-Ranger-TV.html -- filmed on B&W 16mm and telecined to "tape masters" for (later?) TV distribution. The DVDs are sourced from those tapes.

So, yes, when breaking down (24fps) frames into even & odd fields for (30fps) recombined telecine, previous fields were improperly superimposed onto the next processed fields, as the old machinery was not fast enough (nor better designed) to cleanly switch from one field to the next. Fortunately, only less-than-half of the previous field became superimposed on the next! This means that corresponding, uncontaminated halves of the same-frame fields can be joined to reconstruct clean fields for full-frame reassembly back to 24fps.
