You could always use Bavel Bansky's I2C LCD display implmentation and it will only use two wires.
I used this I2C GPIO port expander -> NXP PCA9554N
If you need something bigger than an 8 port extender, try the 16 port I2C extender -> NXP PCA9555N
Just makes sure the LCD display is 3.3V. No need to buy the serial edition IMHO as it wastes pins and is more expensive than the I2C option.
You're also going to need a trimpot of sorts -> 10K trimpot
