Would this Work? My Interceptor Design

This is one of my concept aircraft I have recently designed and drawn. I would like to know if it could work as a real aircraft :confused:, any comments. A few points with this aircraft are:

Wing Design, loosely based on that of the Valkyrie (folding wing tips) and the TSR2.
Tail Plane, when moved, it re-directs the jet exhaust massively increasing effectiveness.
Four Jets, mounted onto the side of the fuselage (this allows space for landing gear and fuel in fuselage) I am yet to decide on what sort of engine to use, any ideas?

Any comments will be much appreciated. 😀
