As I am searching for the right screw on Hasselblad quick plate, this I came across today, which appears to be new on the market. There used be something similar years back. I have not looked into it any deeper, but appears to be direct replacement of Hasselblad bottom plate to go Arca standard instead. I used to think this way, but now have pretty much full set up for what Hasselblad made, yet I know there is logic in going Arca's way.
I have one, well two. Not sure it's the same brand as yours. One for the SWC and one for the 203FE. The SWC one works great, but the V one is too close to the bottom of the 203FE, so that my tripod head was destroying the two rubber feet on the edges. Took me a while to realize that had happened. I just recently bought a set of replacement feet from Thailand.
@Richard Man I actually do not have these, just posted this link as questions about switching to Arca keep coming. Looking at the plate I linked, there appears to be sufficient space to clear the feet though, but I cannot confirm. As per yours, anyone looking at it should ask for height measurement before purchase. It should be at least what thickness of original plate is.
