I agree that this is what you want (or need) for *this* case, but you are
not allowed to alter this request after the resources have been granted.
Otherwise slightly less honest or competent users would completely mess up
the internal accounting.

Have you thought about staging the job?

Assuming the job starts with '-l lic=1'.
Within the job script, you determine if the job specified 'lic=1' but is
actually running on host with node-locked licenses (we'll call them
    SGE_SINGLE_LINE=1 qconf -se $HOST | sed -ne 's/^complex_values *//p

If the job script is running on such a host, you could spawn off a second
job that has '-l licNodeLock=1' instead. This job would target the same
host, perhaps with a second queue?
The first job would then exit. To ensure that the second-job starts
immediately, you could assign a very high urgency to the licNodeLock

One drawback of this solution is that a floating license is always acting as
a gatekeeper to the node-locked licenses.
