I am guilty of being the wallflower, due to nerves, and sometimes it's nice to just stand and read other people's RP. It's such a big step approaching someone, and I've had more negative experiences than positive ones, which makes the next time all the more difficult. 
I don't think there is anymore someone can do than be encouraging, and welcoming, which most people here are already, and taking time from your current RP group to initiate RP with some of these flowers. But that's a big, selfless, ask, and while would be awesome not one I expect people to do.
Bigger actions like the round of drinks mentioned above is a really nice way to get lots of people involved, and an open invite that isn't as difficult to approach as, say, "/em sits and reads their book". You are reaching out to people, and then it's up to them to make the effort and be brave and go for it.
As a different solution, we could make a thread purely with ideas for conversation starters if people are stuck, and for those whose characters wouldn't necessarily start a conversation it might give them other ideas (e.g. accidently bumping into someone).
