I would suggest a claim period (30 days?). Have the bot with eternal rewards will lead to scammers trying to create ways to steal accounts to guess previous rewards. Also, it does not make sense for non-active users to be rewarded (for me).

I would also suggest that the rewards have the same algorithm as the normal swiftnodes. To further prevent the creation of ghost accounts just to increase the chances of rewards. So, the longer you have an account, the higher it will get (up to a period, let' say 30 days too).

For last, any non claimed amount, could go back to the next mined block as an incentive.

Will start bottling my beer... but comments are welcome. And of course... approved! Love the idea.
