No, this is not an option. From the policy [1]:

"the two different packages must not install programs with different
functionality but with the same filenames. ... If this case happens, one
of the programs must be renamed."

The packages provide programs named jdiff with different functionality.
Hence, one of them needs to be renamed. If no conclusion can be reached,
both of them need to be renamed.
