The best advice I can give you is that you don't have to include anyone you don't want to in your group. You are totally in control of who comprises your party.

One thing I will say is that you do have the option of asking Imoen to return to the mainland on her own, strange as that may sound, but it's your choice and doesn't affect the game.

Guilt-free sneaky option + probable SPOILER:

If you have Jaheira in your party and you don't take Imoen when you rescue her she will complain and possibly leave. However, you can pick up Imoen and ditch someone else then quickly reform your party and get rid of her & take the other member back, and she says she will meet you at the Coronet! 2 cautions though: 1) I haven't made it back yet, so I don't know if she makes it to the tavern, and 2) quicksave before you do this in case you can't get your old party member back; it worked for me but you never know.

NO! When you're in the asylum, either leave someone behind BEFOREHAND or never see him/her again. Made a mistake before with Viconia, and had to cheat to get her back... Memnoch, you're telling me that Imoen doesn't really make an impact afterward?
