You should be able to do this very thing with the variable config block.
Provided that you like the format of conf files. -Josh

It would be nice. Though you can get away without the ability to embed

With the current framework, I usually suggest encapsulating logic into
python modules or hier2_blocks, that grc will call into. Post
processing the output is a bad idea.
Id love to see multi-line editable parameters. And to go with that a
function block of some sort. Howabout a block that imports arbitrary
python code from a file and writes it into the generated code?
Although thats only one step away from the above mentioned method.

Abandoned the timer idea.
My goal was to be able to save the values of the GUI parameters in a
file whenever they changed. But
realized that the GRC "engine" already has dependency graph logic
wired in. So I defined a variable,
that relied on the output of a "save the variables" function,
imported from a custom module. This
function takes flowgraph variables as parameters, and saves 'em.
The appropriate "set" functions within the flow-graph end up calling my
"saver" function, and when
the starter shell script comes up, it checks to see if there's a
"saved variables" file, and if so,
passes those values on the command line to the python flowgraph. Easy
as pie.
Still would like to know what the "official" way to get an interval
timer is from a GRC flowgraph, though.
The gr.timer class doesn't appear to have a corresponding python class.
