RS Will buying Rising Storm Digital Deluxe unlock bayonets in RO2?

I have a friend who says he wont play RO2 without the bayonets, he is thinking about buying the franchise pack to get RS but steam doesn't let him buy it because he already owns RO2, so he would have to get Rising Storm and Ostfront (just to unlock the bayonets) separately and that one is not on sale.



Is there any solution for him that I'm not aware of?
