How far will NH pass by Pluto?, - and will it be possible to effect a meaningful course change? Options

[Guest_Oersted_*]

So, from what I gather, NH will pass by Pluto at a speed of around 14 km/s. I know it won't be able to slow down in any way, and will continue into deep space afterwards, but is a substantial course change envisaged at Pluto, or will it fly by so far away that the course change will be negligible?

I realise that the instruments must be optimised for a pass at a certain distance, but what distance is that and could it possible by reduced with no ill effects?

It would be mindblowing if a low pass over Pluto could be planned so that NH will fly close by Charon as well, wouldn't it? - Or maybe even - to go really out on a limb - a few high-speed figure 8's around both bodies, before the probe continues on its merry way. Would that even be physically possible?

At least I'm not suggesting aero-braking if Pluto turns out to have a tenuous atmosphere.
