err, a DI signal generally requires a mic preamp to boost the signal from instrument level to line level. What you say here isn't true. As a gentle sidenote, if you're going to have a tag that reads "engineer" you should probably learn the difference between mic, line and DI levels, and what circuitry is involved with each of them. I'm sure you do know really..it's just misinformation like this can easily confuse.
I can't comment on the 003, but going into the LINE inputs on a 002 doesn't bypass the gain pots, so is unlikely to bypass the preamps themselves - probably just pads them to accept line level (not an uncommon tactic, I'm pretty certain someone who's a better electrical engineer than me has stated this is the case with the digi interfaces).
You don't NEED to buy a new converter - I certainly wouldn't think the ADA800 behringer is going to be an improvement on the 003. why not just try for yourself? compare the same signal going into channel 1 and channel 5. If you can't hear a difference - no need to worry, get on with recording drums! Short of overkilling the problem by buying a whole new converter you don't really need, there's not much of a problem.
