LOL. You and @dennism got me thinking about this.

My thoughts thus far...
OOO Pie Crust 2.5% - it's your basic pie crust.
FA Graham Cracker 0.75% - if a graham note is desired in the crust.
--OR--
TFA Pie Crust 2.5% - it's another basic pie crust.
FA Graham Cracker 0.75% - if a graham note is desired in the crust.
Adding 0.5% SSA Waffle with Butter would add a very light fluffy bakery note to the crust. It would also add a nice butter note to the pie.
INW Shisha Vanilla 1% - adds a light touch of vanilla.
SSA Whipped Cream 0.75% - 1% --- for a topping, moisture and mouthfeel.
If desired: WF Crumble Topping 0.5% - 0.75% --- for a streusel-like topping.
Then add SSA Juicy Cherries as desired.
So something like this...
OOO Pie Crust 2.5%
FA Graham Cracker 0.75%
WF Crumble Topping 0.5% - 0.75%
INW Shisha Vanilla 1%
SSA Whipped Cream 0.75% - 1%
SSA Juicy Cherries - whatever % you desire
If a graham note is not desired then leave it out. Or add 0.5% SSA Waffle with Butter.
That's where I would start and then tweak to taste.
That would also work as a pie base minus the cherry. Then any fruit, or fruit combos, could be added. It would also work as a base for a butterscotch, or caramel, cream pie.
