Perhaps a redirection like \setlayer[...]{\setups{layersetup}} might also 
work (untested).

There is no point in not loading the fonts in the begining if one would 
then have to come up with clever ways to force loading of a font. I hope 
that there is a more robust solution so that

\setuplayer[...]{...}

\starttext
...
\stoptext

just works.

One could also use \starttext ... \stoptext here.
