why not ? It is about 2 day work, but you can use my Fntcreator
http://jansoft.aquasoft.cz/delphicomps.html#fntcreator which is designed to prepare font image for later processing in bitmap editor (like Photoshop).
Export consist of two files - bitmap and widths file.
"Bitmap" use as alpha channel and texturize it or do what you want. Save as another TGA/BMP file and then use VTDManager (downloadable from my pages) for compiling with "width" file into FONT.
