Sure, you *can* do that, but it would be insane to do so.

We look up the neighbour table entries on every single packet we
transmit from the kernel in the same exact way.

And it was exactly to get rid of a pointer in a data structure.

I very much expect that the lifecycle management issues would
be completely different, but I'll admit to having little understanding
of the details of the neighbour table.
