You should really look into the history of altcoins because I'm positive one with a constant mining release schedule has been done. One issue with some of them has been premining but if it wasn't premined and was reasonably well-known at launch it probably stands as a good test of whether something like it will ever work. Funnily enough the altcoin that has done the best has changed very few parameters.
