Currency return for mythic/empys/ergons?

I know it's not likely but what are the chances of adding currency return for mythics/empys/ergons? Relics get 30 hundred pieces back which is roughly 1/6 of a relic. Doing the same for mythics and ergons would introduce a lot more of the currency into the population since a lot of this currency is extremely scarce. I know there no alex, plate, or bayld 100 pieces, but maybe along with adding this features this can be implemented. Say something like a cat's eye fragment or something along those lines.

Just throwing it out there.
