If your goal is merely to not have to plug things in behind the machine, I would suggest that you buy a handful of cables, bundle them together, and be done with it. If you really want to hack something together, though, Radio Shack sells blocks with 8 RCA connectors suitable for mounting in a box. Or use 1/4" connectors. Either way. Or get a $30 patch bay on eBay and use RCA to 1/4" connectors to plug into the back of the patch bay.
If, on the other hand your goal is to fix some problem you're experiencing with the interface (e.g. noise issues). If so, isn't that like trying to retrofit a Ferrari engine into a Pinto?
If the 1010LT isn't doing what you need, you probably shouldn't try to hack it to make it work. Sell it on eBay and upgrade to an interface designed more recently. When the 1010LT was designed, quality components were a lot more expensive than they are today, so they cut a number of corners that IMHO would likely not be cut today. (Bear in mind, when this was designed, the price of gas was still under a dollar per gallon.) In my experience, the difference in sound quality between the 1010LT and even the relatively modest FIREPOD hardware was breathtaking. My 8Pres were a further step up from that. As always, your mileage may vary.
About the only thing you can really do breakout-wise that will improve sound quality in any useful way is to get an eight channel preamp and disable the built-in preamps (which you should do anyway—the built-in pres in the 1010LT leave much to be desired). Beyond that, it is what it is—an unbalanced, 8-channel line level audio card with a kind of muddy-sounding top end for some reason. Its biggest problems are inherent in the design and can't easily be fixed. Well, I suppose you could add a two-channel S/PDIF pre, but....
