What about using a filter before calling TeX to tag strings of Greek
character with \textgreek?  I don't see a solution within TeX while
using the LGR encoding.

In general, using different scripts in TeX without tagging is always
problematic.  You could try the CJK environment (part of my CJK
package) with UTF8 encoding which maps Unicode to subfonts -- your
example would work with fonts like cyberbit.ttf out of the box -- but
this has serious disadvantages because there is no kerning between
various subfonts (just think of accented Latin-1 characters which are
in subfont 01, while ASCII characters are in subfont 00).  In case you
are restricted to modern Greek, only glyphs from a single subfont are
used, so it may be an adequate solution.

I've attached the UTF8.tex sample file from the CJK package.
