Heat berries and 1/4 water over medium heat. Simmer for 15 minutes, stirring occasionally to break down the berries. Pour into a strainer set over a bowl and press the pulp and juices through the stainer, into the bowl. Combine 1/2 cup sugar and 1 cup water and heat until sugar is dissolved and the water is clear. Add puree, simple syrup, lime juice, liqueurs, and tequila in a small pitcher or carafe. (If you have trouble finding blackberry liqueur, omit it or replace it with a couple extra tablespoons of blackberry puree). Stir well and serve over ice.
