Integrated training is expensive and will always be a significant investment. There are many pros and cons. The only thing we know for sure is one needs a licence to apply for a job. Without it you aren't getting anywhere. I've never heard of applications being filtered by medical restrictions over eligibility. Airlines conduct computer based assessments to filter through the rubbish these days. Sometimes you won't hear anything, that's just the luck of the draw.
A multicrew OML would be pretty useless if what you are saying is fact. Out of interest do you have any experience to add merit to your advice?
