I wouldn't bother charging them with points for the mecha, becasue the Valkyrie mecha are not actually owned by them.
I mean, if Hikaru actually went and _bought_ the VF-1S "Skull-1" as military surplus after it had been decommissioned, then yeah, he'd pay the points for it then. But then, the GM could also feel free to impose some disads on the mecha in order to help him afford it in points. Say - maybe take some activation rolls on some systems, since he doesn't have a ground crew to help repair it. Let's face it, military jets are hanger queens at the best of times. And a transforming mecha is insanely complex compared to that. For private ues, you could impose restrictions like that.
The reason that the Valkyrie doesn't have "hanger queen" disads and is always ready to go while owned by the UNSPACY is because of the maintenance and ground crew. And Hikaru and Roy _only_ use theirs during missions and under orders. You don't need to stat the disads for a mecha like that unless it becomes an issue.
Just my .02 cents.
