MIK has often noted that epoxy can accommodate gaps as large as 4mm, so you should be within the margins of tolerance. The key will be to make sure you let the plywood sides take their own shape as you secure BH2 for gluing. Using screws to hold is the recommended technique; you'll just have to be sure to screw only at the corners of BH2 and not within the flat sections. Later, the frame arms will go in and have to be shaped to fit anyway. At that point, you'll be covering the error and you'll be right as rain.
Hope that makes sense. If not, I can throw more words at it.
