Possible?
If I have understood you right, you want to buy a USA-LON-XXX-LON-USA ticket. You want to fly USA-LON and then stay in LON for a bit. Then you want to fly LON-XXX merely to position to XXX, and then fly all of the inbound half XXX-LON-USA. Is that right?
On the assumption that this is what you want to do, then I wouldn't expect you to have any difficulty asking for the bag to be checked USA-LON only - after all, you are then stopping in LON.
In addition, it is possible to fly LON-XXX with no checked bags, XXX-LON with no checked bags, and then check in a bag at LON for LON-USA only.
However, you'd need to make sure that you have enough time after flying XXX-LON to collect the bag from wherever it is, and then get back to check it for LON-USA. In particular, you'd need to have contingency plans against the possibility that your XXX-LON flight is very delayed.
