Defenitely the idea is very interesting. But as for me I'm tired now to participate in different bounties. I will stop doing them after finishing my campaign. But regular payments in ethereum is really great.
You were tired because you used to work many months for useless tokens (in most cases). But Tokpie's solution allows you to sell up to 50% of stakes for Ethereum as soon as they appear in a bounty spreadsheet. Therefore, you highly reduce your risks. Also, it reduces the risk of token price dump when a token goes to exchanges because impatient hunters sell out some of their stakes.
Actually, I think this is the only way to save the bounty market.
