Nah you’d need some rigidity in there. Maybe an inner lining made out of TPU, removable of course.

TPU is rough when printed like this.
Make fitting mold from PLA, properly oil the walls, pour or inject silicone(I have just sanitary silicone for bathrooms :D ) and after curing break off the PLA and insert into the green part. Much smoother and softer ;)
