IMHO, it might affect your chances as the airlines will be able to produce their own using their equipment and training them in their SOPs and if you don't have the 75k they ask for then they might give priority to the ones that do.
I've seen it happen. A guy with 75k vs 2500 hrs - guess which one they picked ?..... it all comes down to economics.
People coming from GA has a very big possibility of being at the bottom of the list.
And yes, I have seen Junior FOs who doesn't even know what a LLZ is and are seating at the RHS being coached.
