Perhaps you could put a gel or filter of some sort over the receiver lens to 
attenuate the IR energy and then fasten the emitter in place with tape or glue 
over it? It's the "precise angle" that worries me though.

My MyBlaster puts out a lot of IR energy, it works fine from the next room, but 
my DISH receiver is not sensitive to where the emitter is located.
