Eh? The following is at the end of the official tpe-omg.tex:

------------------------------
\starttypescript [OmegaLGC]

  \definebodyfontenvironment
    [omlgc]
    [default]
    [interlinespace=2.8ex]

  \definetypeface [omlgc] [rm] [serif] [omega] [omega]
  \definetypeface [omlgc] [tt] [mono] [omega] [omega]

\stoptypescript
-----------------------------------

and \switchtobodyfont[omlgc] is used throughout m-gamma.tex. 
And it works:-)

Are you sure? I get 

This is a test omlgc at 14.0pt

in omlgc of course. 

Are you sure there's not a bug somewhere else? I have my own private fonts

\definetypeface [mtnaskh] [rm] [naskh] [mtnaskhi] [mtnaskhi] [rscale=1.6]

and when I do a switch to omlgc it works fine.  I always enclose omlgc in its 
own group as well. But when I switch to cmr in its own group it does not work 
at all.

I bet that if I replaced all the fonts in type-omg.tex with cmr it would work 
with no problem. There must be something else afoot.

I will study the xchange between u and Giuseppe and see if I can make sense of 
this. Stay tuned.
