Extend built-in SP web part possible
Sorry, this is not possible as you outlined and there is no expectation at this time to make out of the box webparts open source or release that code.
My recommendation is to check out the huge samples repository available in the PnP Community. There are webpart samples there that might have the functionality you want to add to the out of the box webpart, or might be code there that you could use to jumpstart building your custom webpart. If your final product could be useful for others to see, considering contributing back to the repository. (The instructions on doing that are on the website below.)
Links to the smples repo can be found at the link below, alongs with a LOT more information on multiple development technologies around Microsoft 365. Good luck!
