It is my plan that when the time comes, I will get all of the hair from my sides and some from the back transplanted to the top of my head to run along the hairline to the bottom of my neck, then SMP and BHT the sides of my head, BHT just to make it look a bit better and add some texture. I'd keep some sort of fauxhawk style until I get too old to use that, then maybe go for a military style haircut. So I do not think your plan is a bad idea.
