Yea, I am quite certain its possible. I've built two PiGRRLs in the past and I am sure that Adafruit's powerboost1000 and control PCBs will work pretty much as you'd expect. Then there is only a question of the LCD panels/ driver boards - someone more knowledgeable would have to let us how much effort (if any) it would take a stock Pi LCD to work with the Rock64.
You were asking about the Rock64 right ? The R64 doesnt have DSI (or TP) - so the Pine64 LCD will not work. You'd need a driver board - just like you do on a RPI.
