If BA were to buy BMI under the tupe rules they wouldnt be allowed to buy an ongoing concern and then lay everyone off, unless they kept it as a completely separate company. BA is also in a recruitment phase. The crews fit BA and are already trained on their fleet type. It would not be very cost effective to make staff redundant then to recruit or at least look at these same staff members for a position at BA. It could also be argued that it was not a true redundancy and therefore subject to unfair dismissal. I am not saying they wouldn't win but it seems like an unnesasary waste of resource and money.
