That would be possible in principle but would require writing
specialized printing methods for lists and dataframes (at least). 

I was thinking of a much simpler approach, keep track of the printed
output and show only the beginning and end of it with elipses in between
hiding all other text.

The problem with this approach is that if you execute multiple commands,
it will hide all the transitory output, even if it is short, and will
leave only the beginning of the first output and end of the last output.
