One would hope that you're also experienced. 
As far as soldering rails, you will find out quickly that they will crack at the joints. When we solder jumpers for continuity on our modular club tracks, I use a small piece of wire and solder that across the track joints. I've found that when I take the shortcut and solder the joint itself, the bond pretty quickly breaks and I have the same problem as before. I see no reason to assume that your idea will not suffer the same fate.
