I once had left out two layers of prepreg in an autoclaved piece. I ground the surface with 36 grit placed two layers of prepreg on it and then put it back in the autoclave for a cure. It became one with no issues.

Give the original parts a higher post cure once de moulded to get a higher tg an you should be ok on second cure

you want to be really sure she n you do second cure tube bag through both pipes when you cure

by seeing your curing cycle they will probably soften a bit when you put them back into the oven.
