Are there Reversed Earrings/Moonlights in the data?

Since theres a Timeless Moonlight(Cape) and timeless earrings, is there by chance any sort of info on a possiable reversed set of earrings or a reversed cape in the data as well?

No.
The only Reverse item in the accessories list, where earrings are stored, is a Reverse Dual Blade Mask.
There are no Reverse capes of any kind.

there only are timeless forms of the cape and earring. only the weapons and basic armor is reversible.
