Actually its quite a common idea and it can work of course but almost invaribly at a cost of a far greater level of expenditure of money, frustration, lost flying time as well as a much greater road block to your ultimate success which you may or may not have the motivation to persevere.

This will also deprive one of the actually very important part of the hobby/sport and that is the social interplay with your fellow pilots most often found in the club environment.
