Your strategy assumes that the visa’s start date is when you arrive in the UK, and hence it is misconceived. The visa’s start date is stated explicitly on its face as an immutable point in time. So the answer to your question is no.
However, people apply for their visas for all kinds of reasons and have all kinds of different circumstances and it is not abnormal for some people to travel after their visa’s start date. There is no requirement that a person travel on the visa’s start date, or the day after the start date, or any time near the start date. Who originates these crazy ideas anyway?
So if you want to travel some time between the visa’s start and end dates, that’s fine. As long as you observe the 3 month maximum lead time, there’s no problem.
