Perhaps you should go check out the main page of the Battle.net (Blizzard app) forum. Nearly all of the posts there are about getting rid of Activition/3rd party games from the Blizzard app. That should be all the indication you need as to our input.

1) Their DPS and weapon ranges combined meet or exceed the equivalant 2h crossbow you have equipped.
2) You are using Archery to further enhance the use of dual HXBs.
3) Their DPS relative to each other is within a very close proximity or identical and their attack speeds are identical.
Just a note on #3. A slightly lower DPS HXB compared to the other can work as long as it has a good amount of dex to bring it up (≥200) and a crit damage % modifier on it.
Be aware though that this is going to be very, very expensive as those HXBs rarely drop with good stats and DPS ratings, and you need two of them of roughly equivalant performance, meaning that you're not going to have a lot of wiggle room in terms of pricing options for them.

There are awesome ways to edit a video, but this is definitely not one of them.
