It's been years since I tried this, I always input parts into a sequencer and then import them into BiaB.

Try filtering out the breath data.

You should be able to selectively route the data you don't want to go into BiaB to the unused of 2 ports, effectively filtering it. As mentioned, I'd try the breath data (cc2) first, as that is extremely dense. Of course, that will compromise dynamic expression.

On the other hand, if you are playing a non-pitch-bend patch (such as piano) you might want to filter out pitch bend, and use the WX DIP switch to convert cc2 to cc11 (expression volume) and see if that works for you.

If you really need both, I would
1) create the basic arrangement on BiaB
2) export MIDI
3) import MIDI to a software sequencer
4) play the WX5 into the software sequencer
5) thin the data (many sequencers have thin data options and you can thin out redundant values or values closer than a particular value - something like "thin values closer than 2")
6) export the melody only as a MIDI file
7) import the melody back into BiaB
8) harmonize

I've had good luck with this method. It takes more time, but if it makes the final product better, I figure it's worth it. After a while you will get a feel as to IF you need to filter any data rather than redundant values, and how much (always save a separate copy of the sequencer file before thinning anything more than the redundant data).

Good luck,
Notes
