My DP batteries fit my GX8, and SD battery fit my Panny G9, so I'd suggest they've been more than friends for a good while!
This is very interesting information that you have shared.
Could you please share more information on the Sigma / Panasonic batteries that can be swapped / interchanged? Between the cameras you have with you.
Battery model nos. will be appreciated.
From what i know and have tried out personally, the Sigma BP-21 used in my SD14 and SD15 is identical to the Pentax D-Li50 and the Konica Minolta NP-400.
The Sigma BP-31 on the DP2s and DP1x i am not aware of any equivalents from other camera manufacturers.

Sattva,
The Panasonic DMW-BLF19 is the same as the sd Quattro battery.
The Panasonic DMW-BLC12 is the same as the dp Quattro battery.
The Pentax D-Li50 is the same as the SD14, 15 & SD1 Merrill as is the Konica Minolta NP0400.
The equivalents of all of them are made by Hahnel, Duracell and many others.

Thank you for the clear, informative answer for the battery equivalents!
Since, i do not have the Quattro family of cameras, the Panasonic equivalents are not of interest to me.
The manufacturers that you have shared, Hahnel and Duracell...they do not seem to have the camera battery equivalents for the Sigma BP-21 and BP-31.
I checked their official websites.

https://www.duracell.com/en-us/
Hahnel does not list Sigma and Duracell does not have any camera batteries listed on their website. Hahnel lists Pentax, but D-Li50 is not mentioned.
