Not intended as such - just that in terms of time and effort for the result, an evening or two copying up into a new logbook might be the best value option.
Clearly north of 500 or so, the bookbinding option starts to make more sense.
I used to have a colleague with approaching 9000hrs of military flying. He'd had three navy logbooks bound together in leather with wings embossed on the front. It was a thing of beauty, and certainly illustrated that these things can be done. Putting the pages into the cover of the new logbook, or getting the whole lot bound in leather doesn't *sound* a problem, surely?
