I wanted to propose that git-filter-branch generic "generalized grafts"
file based filter should be accompanied by extending gitk so it
understand this format to...

...but after reading wonderfull suggestion to create new commits with
corrected contents, and insert them (replace older version by them)
using grafts, thought and brought independently by Dmitry Potapov and
Petr Baudis, I think that you would be best with extending gitk to
support this way instead.

You would have to extend gitk to maintain reverse revision mapping
(from revision to its children), and then you would be able to edit
history interactively from within gitk, with gitk correcting its
internal structures to redisplay changed commits, and creating commits
and doing grafting behind the scenes for later git-filter-branch
run.
