I have a friend who does wonderful prints from paper negatives.
He uses the modern "oil" sold for the kerosene lamps (not actually kerosene,
odorless as well).
The old time wick lamps for when the power goes like you have inside a
house.
I don't have the name of hand but can get it if you can't figure it out.
It's usually red or yellow in color and many hardware stores carry it.
Target, Home Depot, Loews, Garden Ridge are all good local sources for it.
I tried it once and after a few days it evaporated from the paper negative.
He makes digital paper negatives then rubs it on with a cotton ball.
Some of the waxes and oils turn rancid after a while and really stink.
Good luck.

#1: From what I've read, The Vandyke process does require 'contrasty'
negatives, so your underexpose/overdevelop approach should be suitable.
#2: I've never done it, but yes, I do agree, oiled paper negatives sure
sounds messy.
#3: If done properly, creating enlarged negatives via interpositives offers
a tremendous degree of control. You've had experience printing lith, so
this should be a relatively easy approach. I've had excellent results
producing enlarged negatives on film. You're certainly not "talking crap".
Best regards,
