So, I came up with an idea for a color change, however, lacking the time to really practice it, I thought I'd post it here and see what you guys thought. Please reply with any refinements, adjustments, or general notes or thoughts you can come up with. If you can do it as intended, please post a video. Feel free to do with this what you will, just please give credit, and only use it if you can really do it well.
The idea here is you have a double displaced atop the deck, in a pushed off position, you split the double with the left hand as you slap the cards with the back of your right hand, and rotate the top card around the deck and onto the bottom as you deal off the lower one.
