I wanna make a banana pie with just sliced bananas and whipped cream on the top

Did it work? I'm sitting on my couch eating whipped topping still in the package bowl with added banana slices mixed in. And I thought about making a pie with just a crust and this mix. I don't want to use extra stuff like pudding. I only want to use this mix, is that what you did? Will it work?

Raw bananas? No custard?
You will encounter your fruit turning black, unless you serve immediately after you cut the bananas.
