I suggest you reconsider.

You asked a question and have been given a standard way of achieving the 
desired outcome.

It's common in OO to use a Template pattern like this.

If you're not interested in finding out how loads of people have already 
solved the problem then why ask?

The methods that require overriding can be prefixed with an underscore 
so that people get a hint that they are an implementation detail rather 
than part of the public interface.

I don't see your problem, other than a vague aesthetic unease.
