Well I can tell you it is Possible as TI and AD sells Developements Kits for there AD/DA Converters that just need a Analogue Front end (Mic preamp/Line amp) but these developement kits are very expensive (about $400 for 2 channels) so are quite prohibitive.... there will probably not be many Kits available for a AD/DA converter as they use allmost exclusively SMT parts which are very difficult to DIY unless you have some very expensive equipment....
You could buy a Regular AD/DA Converter interface and just DIY the analoge front end...That is pretty much what I did ,I use a Delta 44 and a Delta 1010LT and I built 10 channels of Mic preamps for the front end...It sounds good and works good and I don"t have to deal with the pesky Digital side of DIY electronics.....
Cheers
