What do I do about the completeness of this name?

I like Sasha by itself but then I put Grace behind it as a double-barreled name, but now I don't really like Grace as much, but the name I have in mind looks incomplete without it. I really like the name Sasha and I don't want to change that part of it. I was thinking of Sasha Grace Jennifer (lastname). I really like the way that looks but I don't know if Sasha Grace as a first name works better than just Sasha and then Grace being the first middle name, because I really like just Jennifer as the middle name and as I said, I'm not as big a fan of Grace as I used to be. What should I do?
