Yes, indeed it *is* feasible.

I'm doing pretty much that, and more, at this very moment.

Have a look at:  

   http://www-texdev.ics.mq.edu.au/PDF/mathsave.pdf

Don't read it directly in the browser; download to disc first,
and get also

     http://www-texdev.ics.mq.edu.au/PDF/mathdljs.fdf

You need *both* files; put them in the same directory.
Now open the PDF file in Acrobat (Reader).


Note that the .fdf file is not necessary for what you asked-for.
It just controls aspects of the user-interface.

Enjoy.
