Place the sliced fruit and mint in a large pitcher and use a muddler to mash them together. Add the agave syrup, tequila and lime juice. Stir, and then stir in the white wine. Cover and refrigerate at least 4 hours and up to 24 hours.
To serve, divide the fruit mixture among 8 glasses. Top each with about 1/4 cup lemon-lime soda and serve immediately.
