A couple of years ago we had a similar incident where a departing 767 had an engine let go at about 50'. Sheet of flame and loads of honeycomb cowling bits all over the upwind end of the runway.
The a/c did a tight circuit to land immediately, though well overweight, hardly giving time for the team to pick up the bits.
As with another thread recently (the 727 still on fire scenario) trying to get down to max landing weight is relatively unimportant under these circumstances. Getting safely back on the ground asap is top of the list. The few remaining bits of FOD are pretty low down on the list, too, under these conditions, where normally we'd clean back to pristine.
