[texhax] Latin Modern with Computer Modern-compatible metrics

[Alex Scorpan]

Hello:

I have an old document that was carefully typeset using the Computer Modern fonts.  I need to replace CM with Latin Modern (eg, to get single PDF glyphs for accented characters, etc).  However, the metrics for LM, being different from CM's (most strikingly at the kerning of quotation marks), change the line breaks, produce overfulls, etc, which is not acceptable for my project:  I'm trying to reconstruct an almost-identical version of the original typesetting.  

So, is there an relatively easy way to get a T1 font with the LM glyphs but with the equivalent of CM metrics?  (I'd have thought this not to be a novel problem, but my search so far has not turned up much (aside from the scary prospect of having to build a virtual font from scratch).)

Thank you,

Alex
