Simplifying Eevee's Evolution

This is just a musing of mine. In Gen I, Eevee was only evolved by stones, and I think it should return to this idea. I never really liked the idea of Pokemon evolving at a specific place, and this would eradicate the need for these areas to be continually put in future games. Moreover, with the creation of new stones, there are enough to cover all the eeveelutions, including my Fakemon: Pureon [link]

Now, the eeveelutions all have a type that was denoted 'Special' rather than 'Physical' before the divide. (This includes my idea of a Light type, that would have been the 9th Special category, thus balancing out with the 9 Physical types). The only 'Special' type not to be covered yet is Dragon. And fortunately there is one stone left: the Moon Stone. I believe this could work, as it does not have to evolve something into a Normal type. (Think Nido's and Musharna).

So, I'm not saying this should be the case, just that it could be the case in any future games; so that it's just as easy to get your Eevee to become any one of its evolutions.
