cant we get a skin trade system?

well i was last busy with mystery gifts adn i got steel legion lux but i bought last star gaurdian so now that skin is useless (unless i want to be fancy) here are my thoughts: what about a skin trade system or something?

something like i give you reaper heca and you give me blood knight heca

and only if its equal to the amount of rp you spend on the skin (these two above were both 975) how about it?
