I had occasion once to judge 33 CanLit short stories, of which I think 28 used this motif. Reading twenty-seven of these stories left me scratching my head, because they were terrible. Then I read the one author who pulled this off, and it was stunning! I voted for it to win, and it won a half dozen other awards as well. Reading that story finally showed me what the other 27 had been trying for, but . . .so not.
I'm not saying you shouldn't accept a challenge, as long as you are aware that's what you're doing, and there is a good reason for you doing this particular story that way. Just don't adopt that motif because it's "in" or because you spent all that energy on developing backstory and are hellbent on working it all in somehow. If there is a simpler way to present your story, chances are, that will make a better story. (Two better stories, actually, if you can write and sell both backstory and current story, separately.)
