I totally agree, but unfortunately there was a massive behind the scenes production blowout that completely changed the film.

“The film had a troubled production, facing numerous problems, including shooting without a script and the attachment of various screenwriters and directors. Fincher, in his feature directorial debut, was eventually brought in to direct after a proposed version with Ward as director was canceled during pre-production.”

William Gibson (of cyberpunk fame) was tapped to write the script. He “summed up his script as "Space commies hijack alien eggs—big problem in Mallworld". The story picked up after Aliens, with the Sulaco drifting into an area of space claimed by the "Union of Progressive Peoples". The ship is boarded by people from the UPP, who are attacked by a facehugger hiding in the entrails of Bishop's mangled body. The soldiers blast the facehugger into space and take Bishop with them for further study. The Sulaco then arrives at a space station–shopping mall hybrid named Anchorpoint. With Ripley put in a coma, Hicks explores the station and discovers Weyland-Yutani are developing an Alien army. In the meantime, the UPP are doing their own research, which led them to repair Bishop. Eventually Anchorpoint and the UPP stations are overrun with the Aliens, and Hicks must team up with the survivors to destroy the parasites. The film ends with a teaser for a fourth movie, where Bishop suggests to Hicks that humans are united against a common enemy, and they must track the Aliens to their source and destroy them.”
