I imagine you are talking about stylistic sets and figures? If so, a good way to take advantage of that power is to use Xe(La)TeX via LyX. Download here.
A quick blurb about it: LyX is a front-end for a massive engine called TeX. It takes advantage of a set of macros and "document processors" to image your text on the page professionally every time. It is a WYSIWYM - a paradigm shift to say the least. If you want a quick walkthrough of it's use (it's the most powerful typesetting program available), PM me.
That is why I suggest using LyX. If you work through fontspec, you can achieve some absolutely amazing control over OTF and TTF fonts. It would also allow you to "use" your font without remapping it.
Apart from using InDesign, this is the closest you can get to it.
As for re-arranging the font - I sense your frustration is attached to the idea that remapping the font would help. It won't. It would be a nightmare. If it's encoded in UTF-8/16 you are going to have some very specific hints and placement for the font. Unless you are experienced with FontForge or an equivalent, you would not only waste your time but grow a few gray hairs in the process.
The most important reason you should try NOT to remap a font would because of the blatant copyright/patent infringement it would take to do it. A font is a piece of software, and changing it would violate the terms of use you made with it. Remember, owning software/fonts does not give you the right to modify it. You only have the right to use it according to the license terms.
