Presumably you can. I'll jot down some notes for you though ;-)

git rebase --interactive (don't do this on published branches).

git rebase --interactive

Define "cut". Possibly "git branch -d" or it's less forgiving
sibling "git branch -D", in case the branch to be removed isn't
fully merged.

Easily understandable:
git checkout branch
git reset --hard otherbranch

The low-level way:
git update-ref [-m <reason>] [--no-deref] <full-ref-name> <newvalue>

There are more options to git-update-ref. The man-page lists them all.

I don't quite understand what you mean by "reconnect", but this might
do something along the lines of what you want:
git checkout branch-to-connect-to
git merge branch-to-be-connected

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
