If it were me I'd probably pull the frets, give the board a re-radius and use some of that wood dust to fill the cracks with CA. If you are careful you can re-use the frets, but fret wire is reasonably cheap so either or. That slightly wonky fret can probably be rescued as well. It's not as daunting a job as it sounds. It's nice to have a caul, but you can use a soft mallet to tap them in. Then level and dress and it should be fine.

I did get also an ebony neck with some slight cracking in it as well. It hasn't affected playability and with repeated oiling the cracks are much less noticeable now.
