My grandparents grew pumpkins in the compost pile. The pile consisted of pig(somewhat aged - there was a pre-compost pile too)pig manure, chicken manure, hay and greens. It sounds absurd to me now but you should at least research the opportunity. Also nice is that the fruits(pumpkins) are created at a distance from the root - so not onto the pile.
I don't think they added any soil to the pile but I was too little a kid to remember correctly.
As a second option, look into acid-loving plants. Composts are supposed to be quite acidic.
