what exactly do you want to replace ?

I'm trying to use the lpegs you have written for mtx-babel.lua, but
instead of rewriting the greek ASCII stuff to a new file, I want to
convert it to proper utf Greek and feed that to mkiv. As I said, it's
a stopgap, but better than nothing...
if there is more demand for that i can consider making a substituter
that operates on the node list in an early stage; that way it is
controlled by attributes and there is no interference with macro
definitions, reading modules and such
Macro interaction may be an issue, but I believe it is still better
for transliterations to work on the actual input strings or on tokens.
For example, you may want to run macros (like \delimitedtext) on the
converted output.
my main concern with that is that one then needs to control precisely
where to apply such translations; for instance turning a< into something
else might also mess up math and adding all kind of extra checking
and housekeeping (for instance when loading modules or whatever in the
middle of such a conversion)
of course when the to be converted fragments are tagged it's trivial to
use lpeg and avoid \cs's
btw, i think that delimitedtext would work anyway as we only replace
"glyph a glyph<" by something else then
anyway, it all depends on the task and hopefully unicode will solve all
our problems (and not introduce more)
