I just ordered some new Stickers for my old Rubik's Cube. But now, halfway through the re-stickering process, I worry that I might have already messed this up and will end up with a non-solvable cube!

Here are my efforts so far:

Is it too late already? Or can you find a way to put the remaining stickers back on?

(Inspired by this question.)

Note: The colour scheme of this cube is not necessarily standard. All we know is that the six colours are red, grey, yellow, green, blue and purple in some order. In the picture, there are three missing stickers around the central corner, indicated by the dark grey sides.
