King Truss Beam options for removing load bearing wall?

Hello, I'm new to the forum but not new to houses. I recently bought my third one (biggest project yet) and I'm working on fixing it up. The house is a single story 24x30 in the main (original) structure with 2x4 trusses (king truss) every fourth one. I am going to remove a load bearing wall which separates the house at the 12' mark. I wanted to ask you guys before I go to the local lumber yard and speak to a project assistant/manager. I checked with the local municipality and no interior building permits are needed, they told me that any interior renovations do not need inspected. What beam options are available given the trusses that I mentioned? I really like the idea of the hidden beam in the attic with hangers which the ceiling joists strap to because it is hidden away with posts which go down to the foundation. (I've seen them mentioned as "blind beam", "blind header" etc but I don't think that this is a viable option due to the king post and both "webs" which extend from the center of the truss to the peak and the half way points. Is a blind header a possibility here? Could I run two beams (one on either side of the king post and strap my ceiling joists to them? I would run the straps over top and down the other side of each to prevent the beams from rolling one way or the other and then posts from each beam down to the floor. I cannot think of any way to temporarily cut out the king post and web posts to insert the beam. Please advise.
