The Obitsu WS definitely matches the MiroDoll NS.
I've actually done that type of hybrid with a vinyl Volks Dollfie Dream NS head on a Miro NS body, which both match Obitsu WS very closely. (Volks DD NS is a near match to the Obitsu/Parabox WS.)
The first picture below shows the group shot. The 2nd doll from the left in a poufy black dress with hat, is a Miro NS body with a Volks NS DD head: (head has been blushed so it appears a little darker than the body.)
Additionally, the 3rd and 4th dolls (guy in orange stripes and girl in pale aqua dress with argyle tights) have Obitsu/Parabox WS heads so you can see how the Obitsu WS compares to the body as well since they're standing close to the Miro body. Again, all the heads have been blushed, but you can get a pretty good idea. The skintone is VERY close. Miro might be a PINCH lighter, but just ever so slightly, if anything:
Here are some additional photos if you want to see more angles:
