Yes
Although, can I replace them with tinned peaches instead? I wonder how that would go...
YES
A definite yes, and now I need to add graham crackers,cream cheese, pineapple and lemon gelatin to my shopping list this week.
"Arrange Dump pineapple on top."

Much better now!

Oh & YES!
YES--and also, this was a wonderful idea for this hot,hot, HOT summer--dozens of nice, cool-looking pies! <3
I'm amazed someone was able to slice those little pieces of pineapple in half. I could never do it!
That actually looks like it wouldn't suck so yes. And I might have to give this a try.
