I would get as much goo out of the crankcase as possible by any means available including through the gear cover, then add a thinning agent, extract and repeat several times. Once able to achieve more oil than goo I would run the engine (no load) with thinning agent added to the oil (25%?) for several oil changes. I have no experience with iso alcohol in this application so cannot comment but certainly Sea Foam and MMO are your friends here.
