We can already do this though by just setting up the beneficiary manually, can't we?  Why is the first stage of the proposal 150 SBD just to do it, when it can't be that difficult to set up as a reward option if creating beneficiary is already a thing..?  Shouldn't your first level, the 150 SBD be for creating the icon?
Just wondering because obviously I don't know.. but I think this is wasted time/energy if this is already a feature we can do ourselves.. 

Set up the beneficiary once and then that username is there as a favourite for the next time you set up beneficiary. Don't be lazy people!!
