As someone that has taken various esoteric routes to complete menial tasks, I get what you are doing.
However, there are an incredible number of people that when faced with a convoluted solution to a simple task who will simply ask "why"? FOr example, in chip races, I used to deal 1 card per extra chip. then I would deal a flop, turn and river. Best hand (or hands, depending on how many chips were being colored up) would win a chip. Way more interesting than "high card", but it was more elaborate than it needed to be, and everyone left on break and checked their stack to see if they won or not.
Additional notes since you've never played roulette:
- 1 spin takes 20 seconds. Add a few more to determine the winner, retrieve the ball, and start the next spin so about 30 seconds. Then recounting/redistributing chips may take up to a minute, so if you don't have to explain anything, and you hit a players number each time, you are talking about 10 minutes.
- Most wheels have 38 slots, so invariably, there will be spins that do not relate to anybody. It would easily be within the realm of variance where you spend 5 minutes with nobody being seated.
In the end, if all you want to do is seat people, then seat them in the easiest method possible. Otherwise, there needs to be a reason it took 30 minutes before the first card was dealt.
