GMG.

[Blodo]

I'd say it's extremely unfeasible, GMG are gas miners. Not shipbuilders and engineers.

Besides, the question is not whether they can do it but why would they do it? They are a corporation, they don't need warships... and even if they got into a war (which is not going to happen), the 80 years war demonstrated they can be far more destructive with guerilla tactics and small fighter craft than the largest navy in Sirius. Their primary purpose is gas mining, escorting and exploration. They can use their own fighters and bombers, and sanctioned kusari explorers. They don't need other stuff, hence a refurbishing project like that makes no sense.
