Yes there is? At least my application. And I'd be happy to support any 
custom format created for the purpose... :)

(http://www.signalyst.com/consumer.html for those who are interested)

I would propose to create custom 8-bit sample formats for DSD purposes, 
similar to the ASIO formats. Practically two main ones, byte with oldest 
bit in MSB and byte with oldest bit in LSB. And maybe the "DSD-wide" one 
which is 8-bit DSD sample.
