Would it be hard to do any of the following?
Gen 2) [Lyra and Crystal appear along with both versions of Gold] Todotile, Bayleef & Typhlosion. Totodile acts as a slower Squirtle with Bite in place of Withdraw, Bayleef heals allies with Aromatherapy instead of Bullet Seed, and Typhlosion rolls into a fast Flame Wheel instead of Flying
Gen 3) Torchic, Marshtomp, Sceptile. Torchic Flare Blitzes instead of Aqua Jets, Flamethrowers like Bowser, and has powerful Jump Kicks instead of Waterfall. Marshtomp has Muddy Water fountains in place of Bullet Seed, a lurching Mud Slap instead of Vine Whip, and slow moving Water Pulses instead of Razor Leafs. Sceptile still Rock Smashes but Dragon Pulses instead of Flamethrowers and Leaf Blade uppercuts back onto the stage.
Gen 4) Turtwig, Monferno, and Empoleon. Withdraw grows lush plants in it's wake, Water Gun becomes Mud Shot and Waterfall turns into a shell first upwards moving Wood Hammer that then falls down quick like Kirby's stone. Monferno spits Embers up in place of Bullet Seed, literally monkey Tail Whips in place of Vine Whipping, and Fire Punches instead of shooting Razor Leafs. Empoleon also Rock Smashes but Surfs instead of Flies (looking like a more horizontal Waterfall) and Scalds instead of flamethrowering.
