GSB, not sure of too many of the details and sure they've been discussed here before, but I do know MPL is coming into play this year, June I believe but stand open to correction. Predicament you mention is worthy of consideration but will probably lead to another modular/integrated type argument so I'll say no more on subject just now. Maybe try EASA website for info, I do believe they're overseeing the licence hence they should have some. If they don't who else does?!
