Sounds interesting. Just keep in mind that when a varnish is run in-line some of the gloss/matte effect is lost when it soaks into the ink. Certainly not a reason not to do it, but it might be a factor in the final product if you do the dot on dot.

I don't want to sound negative because we printers love doing stuff like this, but you're not going to be able to see what the final piece is going to look like until it's dry. By then you've put money into something that maybe didn't give you the effect you wanted.

Just an FYI.
