I don't know the details of the filters that work on pixels ('blend',
for example). I hope a knowledgeable person will respond with
suggestions.
I'd like to experiment with a filter that mixes pixels from 2
progressive streams on an alternating checkerboard pattern. Got any
suggestions?

Have a look at the "maskedmerge" filter. In your case the mergemap file
would contain a pattern of 0's and 255's. This file can be generated
with "geq" filter (see the example in chapter 2.107).
