super family

Sans + Serif pair with identical metrics?

Hi all,

I'm looking for a pair of a sans-serif and a serif typefaces which have identical metrics to each other. The only genuine one I can find even mentioned is McClatchy super-family, but that's a custom commission. Luzi Type's Messina almost hits the mark (and both the sans and serif are perfect style-wise), but they differ just a bit.

Does anyone have any suggestions? Thanks in advance.
