Check with your fab houses whether they can do partial-Rogers boards. Might
be the ticket here.

I had a quote a couple weeks back on a 4 layer board done all-Roger vs.
half-and-half... there wasn't a huge difference; half-and-half was only ~15%
cheaper. This was prototype quantities, though, so I imagine you're just
seeing how little the board material itself plays in the overall cost.
