No , not at 5 months old.
Best to wait til about 12 months old as there is a very tight hairpin turn the GIT in hatchlings and juveniles that is prone to blockages and tends to straighten out as they become subadults.
Superworms are not an insect I'd use as staple anymore than I'd use mealworms as a staple for any bearded dragon.
Stick to crickets, roaches, BSFL (large) ,and in the case of your dragon any size silkworm over 1.5" long is fine (and can actually work out very economical as a feeder if you give a couple large silkworms per day as a staple ( a large silkworm is equivalent to 10 - 12 med crickets in mass )..
