Yes, it does look like it can be done, but it will not be as straight 
forward has it is now.

The basis is here:

At this point, I have no real idea how to extract the IP, hostname etc 
and no real way of testing, because even though they have taken the 
decision to EOL isc-dhcp-server at the end of the year, Debian only has 
usable Kea packages in Bookworm.
