Take an existing brand, and give it a new flavor.

Mine:

1) Pepsi(and Max) Orange. Orange colored, orange flavored Pepsi(and Max) cola.

2) Mountain Dew Tropics: Pineapple Coconut Dew. Sweet Pineapple with a hint of coconut. Yellow color.

3) Dr. Pepper Orange: A smooth Orange drink. Dark Orange color.

Pepsi Green Apple
or
Pepsi Mango twist of Lemon

Josta Rebirth. Josta with sugar instead of HFCS. That'd be tasty. And awesome.

Mine would be THE ORIGINAL PEPSI THROWBACK!!
