So my partners olds have a whole heap of blackberries growing wild on their property and if i pick em, i can ave em. Partner is making me pie, as she should

From my research of Doggers previous posts, i plan on washing them, freezing them, then squashing them and pouring the almost boiling wort on to them. Racking after 5 days. Not too much on the hoppy side.
Anyone see a flaw in my plans? Recipes anyone. Was thinking a wheat kit, plus wheat malt, wheat yeast.....
Cheers and funny coloured beers
