\definefontsynonym[cmr10][aer10][encoding=ec]
\definefontsynonym[cmr12][aer12][encoding=ec]
etc

we can add those (in the context way). 

If someone wants to test the attached file ... seems to work here, that is,
when you add the following to cont-new.tex (apter \unprotect: 

\def\resetfontdefinitionfile[#1]%
  {\letbeundefined{\c!file\f!fontprefix#1}}

I tested it with: 

% output=pdftex

\setupbodyfont[aer] \useencoding[ec]

\starttext

\nl \bf \hyphenatedword{doordefini\"eren}

\stoptext

Technically it comes down to: 

- remapping font files
- making context forget that cmr is defined 
- reload the cmr font definition 

so, it's not that complicated. 

If you want to default to this font: 

  texexec  --make  --bodyfont=aer  de 

should do the job
