Given that Amodel are cranking out a 1/144 series of this aircraft and AZ Models have recently reissued the Gavia 1/72 kit of it, maybe we could have some fun with it.
I'll kick it off with this, which I saw this past weekend at the season opening of the Kunovice Air Museum:
It was done as a joke by a flight school, but it's seriously cool all the same.
Considering how the main gears of the Turbolet retract, that is exactly where you don't want rocket pods to be if you want to keep the tires intact and usefull for landing.
However, the ground clearance certainly shows potential fitting for some gun pods or bombs.
If you put a pair of gun pods on an L-410 rigged out for skydivers, you could concievably insert a special forces group and have the potential to give them some degree of covering fire.
As the Turbolet's wings are also strong enough to carry tip tanks, a couple of pylons under each wing for rocket pods in conjunction with gun pods on the fuselage would make a nice light coastal patroler.
Removing the big skydiving door at the rear would also give you a place to put a manned gun station.
