be more entertaining to do it to btc testnet 
Give me a plan on how to do this instead and I'll consider it. My impression is that I would have to get new testnet-related code into the code for the main bitcoin client. I could write the code and create a pull request (I guess), but I see no reason why it would be accepted.
It will be more effective on the mainnet if the goal is to put an end to the continual debates about making Bitcoin pos.
Make it a modular change so it can be kept current.

Debates is what keeps us alive
