Is It possible no graphic calculator get more options

[ucastrobr]

I go to do a test. They only allow no graphic calculator such as the HP 12C or Casio FX82 MS. Is it possible to put more options in those calculators to solve problems with statics like modern calculators? I read about cheating calculators, but I don't like it. I just want more functions and options, like a Casio FX 991 classic. 
I search something like hacking the Casio FX 82 MS upgrade to a FX-570M or cheating calculator link bellow.

The WP 34S packed a lot of functionality into the HP 20b/30b hardware, so this kind of thing is possible. It's a lot of work and requires re-flashable hardware.
