I'd try a regular SansAmp Bass DI and try using the BLEND and DRIVE controls to see if you can get the right mix of distorted and clean tones.
I use a Bass Driver as well. I have a Bass Driver DI set-up mostly clean, then use the Para Driver for the dirty/distorted part, then mix them both with a Boss LS-2.
I bought one anyway to try, if I don't like it, I may pawn it off to a bandmate...
