I don't know about the Reon chip, but to expand upon some of your thoughts...

The 4:2:0 to 4:4:4 chroma upscaling in the Oppo BDP-83 seems to be able to retrieve more color resolution from Blu-ray discs than any other sub-$2k player. It uses an Anchor Bay scaler. So it is possible to improve upon even Blu-rays.

Also, finding a DVD player which output 480i over HDMI is a bit difficult. Using 480p as an input into a scaler does have drawbacks, if it was de-interlaced poorly in the player (e.g. not taking into account film and handling everything as video--which is what the PS3 does). Again, Anchor Bay has a PReP - Progressive ReProcessing technology which re-interlaces progressive video to redo the job correctly.
