Try Neutraface from House Industries.

Neufville has lots of Futura variations, including non-lining figures. (I'd link directly to the sample page, but the site uses frames so I can't.)

Sad the Neufville Futura SC are mostly reduced versions of the larger caps, they don't fit.

The Foundry's Architype Renner includes text figures, as well as loads of
funky alternate characters based on Renner's drawings.
