I don't think it's possible to ask a stupid question here, since we know so little.
My guess is that the original design didn't get picked up. Maybe they brought in CAC to help and came up with Sky wing. That was probably a technology demonstrator. That probably didn't get picked up, so they went to spend more time working on the GJ-1 project and then the soaring dragon project. Maybe now they are going back to Skywing design because Soaring Dragon is not achieving the specs? It seems unlikely PLAAF will need 2 designs with similar roles from CAC/GAIC. Or maybe PLAN and PLAAF require separate designs.
Thanks ... or maybe - that is my estimation - that Soaring Dragon II will be a surveillance / recce UAV, while Sky Wing II "could" become more similar to the US Avenger a striker UCAV, that could eventually replace GJ-1 later.
