Thunderbird Feature Suggestion: Ability to sync across profiles for local address books

[CopticMike]

Hello, I first want to say thank you for working hard to make such a wonderful product! Here is the feature idea:
For local address books, that dont rely on IMAP or other external syncing, but are stored locally to have a feature that allows them to sync across thunderbird profiles. 

Profiles that are capable to sync are local to each other, so for example in Windows both profiles would be stored right next to each other in "C:/Users/username/AppData/Roaming/Thunderbird/Profiles"

Thanks for reading, and I would love to hear a reply 😄
