The problem isn't the population. Bedrock can handle more than that. London isn't sinking because of all the people (and London is huge!), it's sinking because the ice sheet that pressed the Highlands deep into the crust has been gone for the last 10,000 years, resulting in the entire island tilting back to where it naturally should be. You could move London's population into the Great Glen and it would not make the slightest difference - London would still be sinking. The ice sheets were a whole lot heavier than a few tens of millions of people.
(Ok, it would make a difference. If the rich people actually lived in Scotland, the transit system and public services would see a thousand percent improvement inside a week. If they were also forced to speak Gaelic, English would vanish in a month.)
