I see some contradiction here... You're proposing to have the skins be a purchasable item, yet you want them changed or called the skins stupid and crap?
The skins are unlocked by playing challenge mode, & its called challenge mode for a reason, not easy mode. So asking them to be sold as a skin pack would negate the purpose of challenge mode, so its a NO.
Besides, if you say the 2 skins are stupid & crap, why would you bother getting them?
