IMHO, just make emblems with all the images you want and like. then put them in a pack and release them. If you start asking, you will have an endless list and you will never finish.
In general, people here like some emblems, others don't, some like R/L emblems, others don't.
So, good look and if you release them, i will be very glad to add them to my game.
