Tip-towing tru the tulips
Seems as though the long distance towing and extra manoeuvering entailed in this scheme will put a LOT of new stress on nosegear pylons and related hardware, all of which are surely life-limited and rated for a less towing-intensive plan.
Probably will be necessary to factor in the negative fuel savings for an increase of departure fuel dumps on occasions when gear does not retract properly, etc.
