Suggestion Pet BODY "melting"

With the next Defeat the Undefeatables event looming, I firmly believe we need the solution to the following problem: getting enough Hearts and Feathers for a single pet takes more than the time that it takes to finish all the progress bars (including the chest one)... and that is an insane time already. Meanwhile, those of us who lack only one or two pets do not need the pet bodies for the pets that we already have.

I believe that it can be solved using one simple recipe (or two, actually):
One recipe that allows us to convert a pet body to feathers, and a second one that allows conversion to hearts - whichever one needs more. Given the low pet body drop rate (so low that some of us, despite having finished the last few events, still lack one or a few pet bodies), the duplicates should be worth at least 10 feathers/20 hearts.
