While this is a very noble goal, it's probably an unrealistic one. I'm not trying to be rude or ugly here, but just laying out the reality of the situation. A pusher jet, or ducted fan jet, are going to require a certain set of skills to fly and land safely and unfortunately you're not going to gain those skills just from flying a trainer plane. There should be a progression of planes that you fly as you gain the skills needed to fly the planes you want to fly. Even after you solo on a trainer you will still be flying for awhile as you sharpen your skills on it. Then a second plane will continue to increase your skill level even more. I know that seems like it will be a long time before you can fly the planes you want to, but like everything else in life there are steps that have to be taken to get what you want to. As I said above, I'm not trying to be ugly here, but I would hate to see a nice ducted fan plane become a pile of splinters because of this.

Hope this helps
