I agree - Omeluum as a mind flayer to use stones could be a decent addition as well (if you successfully save him).

Short trip to Menzoberranzan could be implemented too - there is a portal to it in House of Hope and it could be a part of Minthara's quest (for example her getting abducted by her house and party saving her - that would both be a decent plot and explain her motives for war with her house in the epilogue, after all she is a paladin of Vengeance).

For Halsin - his quest could involve dealing with Shadow Druids and even shortly travelling to Cloakwood. That is also a possible character arc for him - when he gets in Baldur's Gate and sees some of its corruption he already starts to wonder whether Shadow Druids might be partially right, so this quest could also involve some moral dilemma for him as a choice between decision that is closer to Shadow Druids philosophy and a decision closer to regular Druids philosophy.
