The British did inter-marry with Natives, at least in North America.
And remember that it was the Spanish that completely destroyed and dismantled every empire they conquered. The British tended more toward a policy of leaving the empires themselves intact, at least on the rare occasion they dealt with established empires with solid social systems, but placing themselves at the head of things and abolishing indigenous practices they found distasteful.
As for whether the Natives are "accepted" as part of the nations the Spanish built, that's debatable. In Peru today, the Inca and other indigenous peoples are still treated more like parasites than like citizens. The Quechua language has such low prestige that most average Inca you'd encounter on the street will flatly deny they even speak it. You can't have any status in Peruvian society unless you have some European blood in your veins. I'm not saying the Inca would have had a great time of it if the British had conquered them instead, and I'm not saying that the English in the sixteenth century could, would, or should have tried, but I have to think that at least the harshness of their treatment would have been less severe and less enduring than it's been with the Spanish and their descendants.
