It's not a terrible idea (someone does something similar in Tekken 6), but the way you go about it isn't the best way to make a ryona video. You're just going online to fight people and recording it, which really is a gameplay video.
I'd suggest finding someone online who you can collaborate with, and make a online fight with the purpose of ryona in mind. Or, you could just fight a CPU with that intent. Try to find some way to make the video look more like it is meant for ryona, and not just for gameplay.
