I stand corrected.  However, the engine will still be considerably
heavier than the CFM56-5C series currently installed on the A340, and
two of them will almost certainly weight considerably more than one
of the current A330 engines (though not twice).  At the very least,
the structures for the outer engines (#1 and #4) will need to be
strengthened, and at worst, the wing may require significant changes
to accomodate the weight of two engines which, in aggregate, weigh
considerably more than two CFM56-5C engines or one of the current A330
