You'll need one of these cables:

Just plug the 1/4 outs from the POD into each BBE pedal and then connect the BBE outputs to the cable above and plug the stereo jack into the FX return of the Vetta.
 
You'll want to setup a patch on the Vetta that bypasses the amp modeling and has the fx loop somewhere in the chain. You also need to stick a plug into the input, otherwise it disables the output of the amp.
 
Hope that helps!

No there isn't a way to do this other than running two amps with different settings.
