IIRC the model for the Baikonur Rocket won't work as a superweapon unless you fix the model and it's animations.
If you really want to make your own superweapon; there is an unused Tomahawk Storm model. You could also convert the particle cannon into a laser cannon, the scud storm into tactical nukes or the nuke into a MOAB-style bomb.
