If it wasn't for the long notice period I'd be tempted to move and just not bother mentioning the job on the CV to avoid setting alarm bells ringing. i.e. you'd have a situation where you left job A in March and started job C in May, you just don't mention job B in the middle unless you are required to disclose prior employment as part of a background check or whatever. It can then give the impression it was just a short break between jobs, not everyone will query such a short gap.
I say tempted because I'm not sure I would actually do that, it's the type of situation where 80% of the time nobody asks about it and it's fine, but the 20% of the time they do ask it doesn't look great if you've excluded it.
FWIW I had a similar situation in the past where I started a job on a Monday and then on Wednesday I got invited to an interview at somewhere I would have preferred to work. I declined because I'd literally just started a job that week and it was my first job after uni. In hindsight I regret it, passed up the chance of a potentially less stressful higher paying job with more transferrable skills slightly closer to home, but as I say that's hindsight, I was too new in the job to really understand what it would be like.
