Looking at the images, from a structural point of view, the situation seems very workable.

Lets assume the new horns are built such that their walls might support a light (structural) load.

Look at the 90° intersection of the two ridge poles (the peaks of the two roofs); from that node, there is perfect triangulation straight down to two more nodes. This means that the primary structure would remain sound and un disturbed by removing the part of the beams that run through the mouths of the horns. Removing this part would require only that you beef up the ridge pole above the cut beams (as it will now be taking a little more load in bending), and that you attach the remaining part of the offending beams directly to the walls of the new horns. This would also help ground the horn's resonances.

I'd also follow Miab's advice on reinforcing and grounding a suspended floor.

As you pointed out, you've finally found a place with many positive points; this gives it, for you, a certain value beyond its purchase price. Over here where all real estate is not only valuable, but down right precious, people do not hesitate to rip into the main structure of very old, multi-floor buildings, often times with 4 or 5 floors of families living above, slip in a few big jacks, add a huge beam, and knock out an offending wall.

Facing and accepting the task is often the most difficult aspect of "big" operations.
