DXB being a long-haul route, a downroute turnaround at DXB probably couldn't be cut much below two hours, and I'd expect at least one of the LHR turnarounds each day to take more like three.
It's the sort of thing that might just be possible if you really had some emergency need to shoehorn all these flights together, and you were therefore prepared to do it on a wing and a prayer and to waste some fuel because the flying pattern really had to get done - but I suspect that that's a scenario that's probably about as far as you can get from what BA will be wanting to do at this time.
