Yes, this is possible. When A8 is released, you could send me such a scene and I'll check how I can improve it with GPU vertex animation.

However you must be aware that for GPU based vertex animation to make any sense, we must allocate as many model meshes as there are frames. So we need 5 meshes for a model with 5 frames, which of course consumes 5 times the memory. I'd say this is tolerable for 5 frames, but not if the model has 30 or 50 frames. You'll then use up all your memory for one single model.

When speed is important, better use GPU based bones animation.
