Butternut Early Remix from Adaptive Seeds is exactly what I had in mind, thank you Diane.
"In 2005, we started growing every early butternut variety we could find, including Nutterbutter, Hunter F1, Butterbush, Early Butternut F1, Butterfly F1, & more. We allowed them to cross freely & have been selecting for early ripening & 2-4 lb fruit with a classic butternut shape."
