Rom idea

[Geezuskryst923]

I'm new, so I don't know if this is the right place to post. I had a good idea for a new rom. Pokemon Eeveelutions. Your only starter is eevee, but you choose from a variety of items. Eviolite, metal coat, dragon fang, poison barb, hard stone, soft sand, cleanse tag, muscle band, sharp beak, silver powder. The eevee would evolve into whichever corresponding item you choose once you meet the right requirements. Level up while holding an eviolite after reaching 100% happiness and KOing 25 pokemon with return to evolve into eeveon. Normal type. Level up while holding metal coat after KOing 25 pokemon with iron tail. Metaleon/steeleon? Steel type. Level up while holding dragon fang after KOing 100 dragon type pokemon. Draceon dragon type. Level up while holding poison barb after poisoning 100 pokemon with toxic. Toxeon poison type. Level up while holding hard stone after being KOd by 25 rock type pokemon. Rockeon/stoneon? Rock type. Level up while holding soft sand after using dig to escape 100 places. Sandeon ground type. Level up while holding cleanse tag after being KOd 25 times and KOing 25 pokemon using frustration. Spookeon ghost type. Level up while holding muscle band and KOing 25 pokemon using double kick. Mmaeon? Fighting type. Level up while holding sharp beak and KOing 25 pokemon using aerial ace(obtainable TM sometime after 2nd or 3rd gym) aceeon/floateon? Flying type. Level up while holding silver powder and KOing 25 pokemon using leach life(obtainable TM after gym 1) insecteon/bugeon? Bug type. After beating elite 4 a lab becomes available to get enough eevees and evolutionary items to complete the Eeveedex.
