When Emacs displays on a TTY frame, the font is out of its control. The font is determined by the terminal emulator or the console config files, and Emacs wouldn't know where to find the font even when told its name. In particular, if you login from another machine, the font used by the terminal emulator is not accessible at all for Emacs that runs on the remote. So I think what you envision is impossible, or at least impractical.
