Flattening form after filling but before signature

Yes, this is possible. But it's tricky, especially with a LiveCycle form. First, LiveCycle forms can't really be flattened like an AcroForm. The best you can do is save the PDF to postscript, and then reimport it into Acrobat. This is of course very awkward.

There is a menu option for signing a form, so there doesn't need to be a signature field on the form. The form could concievably be signed after it is flattened. But this isn't very user friendly and it will not work in Reader.

Maybe you shuould consider locking the form fields by making them Read Only, instead of flattening. This is the easy solution.

Server side processing is your other option. To work server side with a LiveCyle form you'll need the Adobe servers. There are plenty of 3rd party server tools for AcroForms. But again you have a problem with Reader. In order for the form to be signable in Reader it has to be Reader Enabled for Signatures. And this can only be done with an Adobe Server.
