I doubt it. The ability of guided arrow to ignore defense is pretty important to its damaging ability.
However, I could see a 1pt double throw barb using lac's being quite effective. Loss of +3 bo, but you gain a ranged attack that's decent (but worse than widow) and the ability to amp. Could do well vs hammerdins or really defensive smiters.
Honestly, try it on your own and see how it works out, though I'm pretty sure playing a "vanilla" BvC with Widow will probably be more effective.
