Allow us to purchase skins without owning the champs.

then automatically have the champ unlocked upon purchase with the skin.

In essence, the champ is technically obtained for free.

I think it's not a bad idea and it helps Riot make more money as people are encouraged to buy skins.

I guess the drawback is that people who're willing to pay get a real head start, but in the long run, it shouldn't make any difference. Plus, it's not like the current system doesn't encourage that already.
