Compelling architectural comparison.
However, do recognize the Steamboat museum was constructed -- with donations -- in the 1990's. At that time, River Market was dodgy, at-best. We guys would walk the ladies to their cars after a few beers at the "River Market Brewery" - out of necessity.
Further recognize the River Market was known as the "River Quay" in the 1970's and 1980's. It was riddled with mob-controlled front companies. Car bombing and contract killings were the news of that day. The rumors are that the stately old homes off Independence Avenue (near the old museum) had tunnels linking the homes. I believe it.
30 years on; the place is unrecognizable. The fact the district extended to the riverfront in astonishing in it's own right. The Hyatt Regency skywalk was disposed in that area. If you smelled a decomposing body in the railroad right-of-way; it might be a dead Opossum; or an unlucky hooker.
The Farmer's market itself was a catalyst to bringing the public into the district. Add a few pioneering stores and venues.
..And then there was the Steamboat museum.
