Display characters with a different size?

[XeCycle]

Hello,

I want to tell Emacs to ignore size specifications in a font, and
use another size instead.  Is it possible?

The use case is, I chose two font for my display, one for English
and common symbols (or, what you'd expect from an English text),
another for Chinese and complicated UTF symbols.  They're of
different size, even on the same size number; it messes up the
display.  I therefore want to tell Emacs to display those Chinese
characters with width twice the same as the former, and height
same as the former.

I searched in the docs and didn't found it.  Afraid it's not
available now.

(emacs-version) "GNU Emacs 24.1.50.1 (x86_64-unknown-linux-gnu,
GTK+ Version 3.4.3) of 2012-05-24 on XeCycle"

Thank you.
