App,

Good thought to identify the musics influenced into Raja's output. I feel its difficult to identify because Raja got influenced by lot number of people at various stages and various degree of influence. The beauty of the part is, we do not know many of them

I feel following people also should be there in your list.

1. SD Burman
2. Madan Mohan
3.Naushad
4.Shankar Jaikishan


I did not know the details of influence of these 4 MD but believe that their impact would be there in Raja's music as raja talked about them at various places.
