The only mu in *CM* is in the math italic fonts, which cannot be
replaced by LM. Actually this mu seems to be the model for the mu in
LM. I think you are talking about the mu in *EC*. The LM-mu is indeed
much better than the EC-mu. Interestingly, for the commen usage 'µm',
IMO the combination EC-metrics with LM-fonts looks best, but that

In which font shape? At least in CM Roman and LM Roman the dollar signs
have identical outlines.

In case you where refering to the section sign §. Here the shape in LM
is an imporvement over CM/EC (though the glyph looks a bit to dark IMO).
It does have different metrics, though, as one could see from my EC-LM
example. This does not cause problems when one tries to replace CM by LM
because the section sign is taken from CMSY, which can't be replaced by
LM. So there are no changes here.
