Fun idea, been thinking about that as well. It's certainly possible to mirror the custom large-number display of the MPGuino. But having worked with various character LCD modules (like the one used here) in the past, I don't think the LCD's backlight would provide the right combination of brightness and contrast to make a workable HUD. For that, you might want to adapt a 7-segment display -- and yes, they can be mirrored: There are a few i2c led-controllers out there which can control the display on the segment-level, and only use two arduino pins.
