This should a 'holy grail' target for amateur planetary imagers. Visual is probably out of the question...
Those with smoothly driven large dobs - 20, 30,40 inch class, get the focal length up beyond 5000mm with an appropriate Barlow.
Video lucky imaging may work. Can you reach 18th magnitude?
What may work better is speckle imaging - sub-arc second pairs can be imaged this way with a 'small' an aperture of 11 inches...
The Journal of Double Star Observations is a good source for potential methodologies...
And with Pluto's declination these days around -23Âş folks in the southern hemisphere are in an advantageous position for the next 100 years or so...
I'll start making the popcorn.
