You will not retain the history on the trunk. The history breaks at the
point that you issue the move command. There is a reason why there is a
'merge' and there are 'move/copy/delete'. They are very different and each
is very necessary in its own way.

My first reaction to what you are trying to do is EWWWWW. You're creating a
huge mess when you want to go back and look at the revision history of your
code. You'll have to try to keep track of cross links between branches- why
does the history of the trunk suddenly stop at revision X and switch to
branch A? Why does the history of branch A suddenly switch to the trunk?
Why can't I look at the history of the trunk older than six months ago
(assume branch A is five months old)? How do I get that history back?

My suggestion to you is to clone the repository and try it out. Then see
the ramifications - you will probably not be happy. I will be much easier
on you later on to deal with the merge than to try to defeat the software
and create problems.
