Here’s an image of a solution shared on the Adafruit Forums for combining your Adafruit Pi Box with one our LCD+Keypad screens for the Raspberry Pi:
Well, for me, I just received my Adafruit Pi Box with the full intention of keeping my Blue & White LCD Pi Plate attached. In fact I really like the setup!

Adafruit Blue&White 16×2 LCD+Keypad Kit for Raspberry Pi: This new Adafruit Pi Plate makes it easy to use a blue and white 16×2 Character LCD. We really like the 16×2 Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 1 to control the backlight for a total of 7 pins. That’s nearly all the GPIO available on a Pi!
With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don’t really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle. (read more)
