I don't really know what to tell you. The ability to do this with very minimal effort already exists. All you do is simply open photoshop/GIMP/whatever, open your monster summon sprite, paste it into the animation reel that Drifty explains how to create, save it and then you have your monster sprite which you can then summon in battle using YEP action sequence plugin.
Not to be rude, but if you had watched the whole video, you would have seen that he does not create animations, just a simple sheet so he can call summon sprites. The whole process of building an animation reel for one monster would literally take less than five minutes. You don't need artistic ability or specialized equipment to do this.
I highly doubt someone is going to write a plugin for this when it is already so easily done.
