Under the assumption that the paper in question is being published in a journal, that might be a bad idea. In my experience, journals will typically take your content and then reformat it themselves to fit in whatever their constraints are (page size, number of columns, possibly starting in the middle of a page, etc, etc). For journals that take LaTeX submissions, they will generally just apply their house style file. For journals that take Word submissions, they will generally just apply their house Word style. For journals that accept either one... see above. ;)
