RWBY OC Crossover: The Two Mercs

These two has their own rivals to deal with, but when these two interact, it seems to be a special kind of rivalry. And after hearing an incident with a blue-haired kid in the White Fang, made wonder...what if these two...we're once...COMRADES!!! DUN DUN DUN!!! ...whoops, wrong emoticon. Little over the top, but there we go!

 I got this idea when I tried to sleep (finally was able to sleep...somewhere in 6 AM!!! )  and decided to make a quick sketch and save it on my computer before I forget. I was about to make Sai's disguised form with Laura, as she wanted to be his friend, but some other time. Reason why I made this (not just the reason above) is that, these two were mercenaries, same age, alone, hatred for mankind, and tie-ins with the Grimm.  I even thought how these two met (I'm really creative and detailed when I try to sleep without any luck). Here's the nutshell, they work together when have the same client, but became enemies afters a certain mission. Should I go to a more detail on their past? It's also a "what-if" pic, so I don't know if they did met back in the day. Or, we could label this one as a filler.
