Taking a plastic VV1 Ranger and converting it into a twin-turret VV22 variant? That's easy, just find a decent turret and glue it in front of the existing one somewhere.
Having to scratchbuild the entire front end because the piece of plastic that makes up the front and top of the driver's compartment fell off sometime before the mini came into your possession(likely during manufacture, going by the complete lack of glue residue), and doing so in spare moments at your office using only bits of styrene and a post-it note or two? That's hard.
