...I don't think anyone would want to buy a ticket to a gala held after a private competition.
Probably why they don't have their way
I forgot to mention, other sports may also have "close calls" ie. the puck hitting the goal post, the basketball bouncing on the rim and falling off the wrong side. Close-calls illicit ooohs of excitement. Figure Skating does not have close-calls, but does have the opposite ie. falls and stumbles etc. Perhaps not as exciting, since I assume everyone feels bad for the skater (unless you are bias against, or indifferent).
All the ideas you have been discussing are good, but they appear to be aimed at casual fans with some basic knowledge. In some cases, I think it may be necessary to go even further back to raw basics.
When I was at a hockey game with my brother and his wife, the wife mentioned it was difficult for her to "get-into" hockey because she did not understand it. As an example, she commented how the whistle just blew and the game was stopped, yet she had no idea why. I responded by telling her it was an "off-side" call. Her response was, "yeah, what is that". I think it is the same with Figure Skating.
Before I became interested in Figure Skating, I had heard the terms "Lutz", "Axel", etc. and knew they were jumps. I knew a double was the number of rotations in the air, although it was not obvious from the name that a double axel was actually 2.5 rotations. I had no idea what the differences were between the jumps. To the new casual viewer, they all look alike (jump up, rotate, land). It was not until I made the effort to search the internet that I learned the differences. Even then, reading the descriptions wasn't clear (that site had too much technical details, and was difficult to follow). I had to read the descriptions several times in some cases. Most casual viewers would not make that type of effort, and would go through life blissfully ignorant and uninterested. The same sister-in-law also mentioned to me on a different occasion, that she wouldn't know the difference between a Lutz and a Flip (she chose those jump names randomly). What is a Mohawk? Is that a type of haircut or a native Indian tribe? Like my brother's wife with hockey, it would be difficult for people to become interested in Figure Skating if they do not have a clue.
Occasionally there are trade shows held for cars, home products, hunting & fishing, wine & cheese. I don't know if there are similar sport trade shows, where local skating clubs can put on exhibitions, and give a brief basic "skating-for-dummies" demonstration between the performances. Perhaps the indifferent can be turned into casual fans, and the casual fans may become avid fans.
