Alter and save swfs without re-compiling?

Hi-

For my work, it would be extremely helpful if I could alter the actionscript
of a swf and save those changes without going through the process of
decompiling and re-compiling. Primarily because of font issues.

I have searched high and low, and cannot find an application that will do
this. I have a bare-bones app that will let you edit getURLs and save the swf,
so I know it's possible.

I already have SoThink SWF Decompiler, and a couple other similar
applications, but this is not what I need. Can anyone point me in the right
direction?

Thanks in advance!
Susan
