Your 192 Digital certainly COULD have use for you. There are several 8 channel preamps out there on the market(and several also have D>A for extra outputs too). If you are fine with 44.1 and 48K recording you could use the Behringer ADA8200 to add 8 more analog IO thru the 192D(actually, you could use 2 of these for 16 more IO). The Behringer is likely to sound as good or better than the Control 24 preamps. If you want to move upscale a bit, the Midas XL-48 is phenomenal on drums
(I have several more expensive preamps but the Midas beat them all)
BTW, if you want higher sample rates, the Midas has AES out that the 192D would work fine with
