Misformonkey,
Anything we do to solve this problem is going to be expensive, however you look at it.
Tourist,
I had forgotten that your barnacled lunatic Mk1 cousins flew around sans NVD. Fair point. All solvable issues though. I still think that making the Mk1 fit for purpose with NVD and DAS and all the other things you mentioned is a better option than selling it to Johnny Foreigner for peanuts if ASAC does not happen.
