I haven't tried it myself so you might be right, but I was thinking of the silver conductive pens from Chemtronics with a conductivity of 0.02-0.05 ohms/sq/mil.
For attachment, I'd evaluate their conductive epoxy or maybe glue down the underside of the component and then smother the lead with the silver conductive ink. But again, just hypothetical since I have a quickturn shop make cheap prototype PCBs for me and either hand solder or use a stencil, paste, and a hot air gun for my hobbyist projects.
