I can confirm that it will work with your main character. In fact, what some people do is when they've gotten so sick of doing all the Candlekeep quests in the Prologue, they'll start a Multiplayer game, clear Candlekeep, watch Gorion get whacked, and have Imoen join the party. Then they drop all their gear to the ground, and Save their game.

Then, all they have to do when they start a new game is load up a copy of that Save (still in Multiplayer), delete the PC, and roll a new one. Start the game, and BAM, you and Imoen are outside Candlekeep, with a load of equipment at your feet. Save, move that Save into the Single Player folder, and play as usual.
