Chris is absolutely right - don't even attempt it.
Can I suggest:
1 - you either re-plan your worktop layout such that the inset is away from the ends of a longer run,
2 - see if a right hand or left hand drainer would make a difference to the positioning,
3 - (last resort) see if you can get a sink with a drainer that doesn't need to be part of the cut-out, and the drainer could then overlap the joint, but the cuts will have to be spot-on, the cuts sealed with at least 3 coats of varnish or whatever, and the worktop connectors properly fitted.
