nope, it won't work and I'll tell you why.
For connecting additional pre's to the 002, you'd need an optical ADAT (lightpipe) interface. And not a stand alone interface (like the 002)
the 002 gives you the option of 4 pres, 4 balanced TRS and 8 channels of optical ADAT.
The edirol dosn't have that connection because it was designed as a stand alone interface. It's like a cheaper version of the 002. And if there's anything I know about these audio interfaces, is that they don't play ball with each other.
So if you are hell bent on connecting additional pres to the 002, then you need a preamp/mixer strictly with no more than 4 TRS outs and/or a lightpipe (optical adat) compatible devise.
Presonus makes a devise that connects with the 002. I think it's called the Presonus lightpipe I/O or some bullshit like that.
runs you something like 600-800 clams.
