I think this would make a good start.
Without automation it's going to be hard, but only if you will have a lot of people buying these tokens. I think that at the start it should be fine to do it all manually - you can just keep the SIM flowing to the account and only sending it to the holders each week or something, it doesn't have to be every day.
I think you are onto something.
Keep it up.
Do you need help?
