Huge Weapons Perk or bonus to ST only to meet MinST requirements

[Icelander]

Is there any way I can model a +1 or +2* bonus to ST, only for the purposes of meeting Minimum ST requiremrnts for weapons and so it would not increase listed damage with any given weapon? With my minimal knowledge of GCA, the only thing I can figure out would be to manually reduce MinST for every weapon it is meant to apply to, but that would mean that the weapon stats appeared wrong, of course.

*Well, or any bonus, really, though the Huge Weapon Perks only comes in two levels.
