Transfer R15 NPC to Rthro?

Wondering if there is any easy way to transfer a R15 dummy to Rthro. I already have well over a dozen NPC’s that I don’t wanna have to insert an Rthro for each one and re-apply all the clothing/packages/etc. So is there any easy way to do this?

You can try exchanging the meshId for the body parts for the Rthro body parts’ meshId.

There is no way to simply do this, you’d have to completely re-do all of them. Or replace the MeshId’s as @Expoxide mentioned. Both in the same case are difficult.
Another reason is R15 is 15 joints,
Rthro is way more than 15 joints, it is probably around 30ish joints. So there is no way to do this without having to add to the NPC’s.

Never mind, what kind of Rthro are you trying to achieve? A more scaled R15 Rthro type, or this Rthro;
