If I recall correctly, 2M red, blue and silver use the same body. 2M bronze and black use a different body. I think you should be good to try the silver stylus on the blue body.
Ortofon blue
I currently use a ortofon blue stylus on a 2m red cartridge.i also have a ortofon silver stylus and cartridge .can I install the silver cart with the blue stylus with any good results?
