The variety pack's randomisation feature is antiquated, but the skins are stil useable. It's now possible to have multiple skins for each ship.
There is also a far better tool for now for bringing these skins into the game, by having the later war skins come in at the right times... SH3 Commander. Jscones has actually already included iambecomelife's skins in the combined skin pack addon.
If you don't already have SH3 Comd, get it at Jscone's website, along with the skin pack...
