It is possible, but it is not user-friendly. Basically, you need to extract the firmware image using CRAMFSCK, update the font files, then create a new firmware image using MKCRAMFS. After that you update the checksum file and then you can flash the modified firmware. This process works was tested by me or my readers for 300, 500, 505, 600, 650 and 700. It should work for 350 with no problems. In order to modify 900, I am told you need to do it in Linux rather than Windows.

I wrote a guide for the whole process, but unfortunately, it's only in Czech language. If you feel brave, you can give Google Translate a try.

When replacing fonts for LRF/TXT/RTF, my SonyFont tool will be your friend:
