As you point out, the bottom line is fstack et.al., where no interaction 
is possible.  The create either succeeds or fails.  With that in mind 
can i suggest considering instead how you might interact with this from 
a UI.  For instance, would this work:
    ->File->Open
       use file browser to open a core file
    <<Core file assistant appears; perhaps pre-populated with info from 
raw core file>>
       - indicates what action is going to happen next, for instance 
indicates the executable it will attempt to open (or don't bother)
       - OK attempts to open the executable or fails leaving the user 
with the assistant
from a cli, a similar interaction might be:
   (fhpd) core foo
   Executable <exe> for <foo> not found.
   (fhpd) core foo exe                 --- the user is right
   OR
   (fhpd) core foo -noexe
another might be:
   (fhpd) core foo
   Corefile .... of arch ... no executable.      --- printed by fhpd 
using stuff from core
   (fhpd) exe ..the-exe...
   Corefile ... of arch ... executable ...      --- intercede the no-exe 
core
Each of these are built round the assumption that the code creating the 
core file is more predicatable (and more likely to throw an exception) 
for instance, interfaces with requirements such as:
   -- create core and must use implicit exe or fail
   -- create core and ignore exe
   -- create core and use explicit EXE
