I'm trying to extrude a face towards multiple faces but I'm not sure how to go about it. 

I want these 2 to be touching but whenever I try a loft/boundary extrude, it either gives me a weird shape or nothing at all. Any ideas would be appreciated. I don't want to merge the 2 solids but I want them to touch each other. I'm getting an error of "At least 2 profiles are required to make an open loft" or "The feature could not be created as it would produce self-intersecting geometry" but I've turned off Merge results on all parts
