I'd be hesitant on it ... though I'd try the mirror trick, as suggested.
It doesn't fit the "rules" but look at this 4PP ... if AlikiGirl had followed them, we wouldn't have seen this beauty.

So I'm thinking ... it just may work!
You could test it the way I did the other night ... cut a strip just the width of one block, the length of the selvedge and layer the pieces. That'll give you a first few to know if you like the look ... and not have ruined the big piece of fabric.
