I don't think having the blades bend like harbringer will make them flexible in the right way. I'm not really all that well versed in the art of explaining why bows are hard to make in RWBY, but I can say that in the past, Phantom has approved the use of  sabers to make a short bow.

If you are looking for a longbow, I think that a cool idea is using scimitars and a robotic mount. A quiver on the back could provide hardlight arrows that are able to be enchanted with dust cells within the pistols. Likewise, the historical useage of scimitars and calvary sabers as cutting swords well suited for horseback combat would make sense.

The robotic mount could alude to Pecos Bill's horse, widow maker. I can help you with ideas if you are interested, but if not, sabers and scimitars are generally the best options, as long as you make sure they are thin enough to provide flexibility.
