1) No
2) CPL and MEP Rating will require 2 separate skill tests. One is a licence and the other is a rating to put on that licence! You could do all of your CPL course on a multi (££££!) but you will still need to have done the 6hours MEP training and a MEP class rating skills test.
If there was a cheaper way to do things, FTOs would already be doing it that way and quoting it as their "best price!"
