keep in mind that mice don't get much bigger than 50 grams(from my limited experience at least), and larger BPs will either need to eat multiple full grown adults for a meal or be switched to a larger rodent.
adults on a mouse diet sounds impractical to me.
for my larger adults I would feed them rats instead, but my subadult/small adults and smaller ballz, multiple mice each feeding has been doing the trick for me.
