Hello knyyghtmareV3,

unfortunately I don't think that will ever be possible.

The main reason for this are the tri-ax weight maps which won't work in Studio, but are which makes SASHA bend so good.
Sure you could replace the rig with the conventional V4 rig and it's sphere zones.
But that would completely cripple the figure and it's bending.

But even if you could build a rig that works in Studio SASHA still would be useless because of many of the morph and dial dependencies are Poser-specific and can't be read by Studio.
But all these are mandatory to make SASHA what she is!!

And there's probably a ton more which i don't know of yet.

Let's face it:
Studio has given up any compatibility with Poser since the event of the first G figure, and since then the gap grew even wider with every new version of Studio.

SASHA's legs aren't long enough to ever bridge that gap.
Neither was she made to even attempt to. She was made for Poser only from the outset on.

Last thought:
I even couldn't provide support for all the hickups that probably would occur in Studio because I don't use Studio.
Nor would I ever have the time to chase two rabbits (Russian proverb: "If you chase two rabbits at same time, you'll catch none").

Sorry for the bad news
