I'm not 100% sure that I understand what you are asking for. REAPER was developed as a windows application. It has been ported to OS/X & Linux by implementing the win32 GUI calls in SWELL. It does use some GDK/Cairo calls right now, but mostly implements the drawing of everything, such as windows, dialogs, menus, bitmaps, etc. In fact the long term plan might be to uncouple it from GDK and just use XLIB/Cairo directly.

That said you can somewhat theme all the OS level windows with SWELL. You can configure most fonts, sizes and colours. Try putting this dark theme file https://stash.reaper.fm/30510/libSwell.colortheme into ~/.config/REAPER. You can generate your own libSwell.colortheme with the Makefile in the SWELL repo.

And yes, as SWELL implements more or less everything that REAPER needs to draw, you could most certainly change or improve it by diving into the SWELL source code.
