My teenage daughter dose something like that. She uses two or three bigger claw clips on wet hair and leaves them in over night and wakes up with lots of root volume and great curls. She's able to get most of her hair piled up on top and places the claws so they don't poke her scalp while sleeping. This works for her instead of plopping. BTW she has thick 3a/3b hair that falls below her bra strap, and uses a LI and FHG.
