I think that if you leave off the silent install option that your other
selections set by command line options are respected in the UI, so the
extra packages you select will show as selected by default once the user
arrives at the package selection page.  Unfortunately, you have to trust
your users to correctly hit the Next button on every page without
changing anything until they get to the package selection page.  Whether
or not that trust is warranted is between you and your users. ;-)

The batch file I wrote for work actually includes a bash shell at the
end of it for post-install actions.  After the actual batch logic, you
can run the goto :eof command to jump the batch to the end of the file
past the bash scripting.  It looks something like this:

@echo off
rem This batch file installs Cygwin with extra packages.
rem It then runs some post-install logic written for bash
rem which is simply appended to the end of this script.

setup.exe -P pkg1,pkg2,... <more_options>

C:\cygwin\bin\sed "0,/^BASH SCRIPT BEGINS/ d" <%0 | C:\cygwin\bin\bash

goto :eof

BASH SCRIPT BEGINS
echo 'Starting post-install actions...'
...
...
# This is the end of both the bash script and the batch file!


I may be foggy on some details, but hopefully, you get the idea. :-)
The only requirement is that the user drop setup.exe into some directory
next to this batch file.  You could even get clever and have the batch
file tell them where to get setup.exe in case they run the batch file
without first downloading setup.exe.  I should probably do that for *my*
script...
