The way to solve transparency for content stream elements is to flatten it (a VERY complex process of rewriting shapes). You can probably get way with changing transparency in annotations/fields to just 1 (or removing the key all together), if you must.
You replace them by embedding the new font and potentially rewriting the content stream with the new encoding values. Neither of these are trivial problems - both will require weeks/ months of development effort - however, they are well defined.
