do you think that in a couple of years (when i will be hopefully with my CPL/IR done) airlines are going to start to recruit just people with this MPL
At the moment this option is not possible.
or maybe they will start to recruit cadets training them for the MPL
This is how it is done but "recruit cadets" may be a bit strong to describe the only UK airline currently involved in ther MPL, namely Flybe. They do pre-select students and give part-sponsorship for the MPL.
You cannot go to an FTO who offers both fATPL and MPL and simply ask to do an MPL course instead of an fATPL. The MPL
REQUIRES airline involvement from the start of the course- therefore you must have already been selected by an airline before you can start an MPL.
