There are just too many issues with the way Speedway is currently in the UK, there is not one huge fix, its loads of little tiny fixes which need doing one by one and then as each one is undone it will divide the fan base etc. and nobody will ever be happy.
What would I like to see? I think there is too much emphasis on league racing, I understand it needs to stay as its been the backbone of British Speedway since the start, but just have league competitions, fans aren't really interested in other competitions they want to see their team make the play-offs and win them! also foreign riders don't want huge fixtures and with the Polish rules relaxing somewhat, then it may entice a few big hitters over with the view of riding in a reduced calendar.
What I would like to see advertised as the main event of British Speedway is the introduction of the British Speedway GP Series, ran over 8 meetings, featuring 12 of the best domestic riders, each rider having 4 rides over 12 heats with the top 4 into a final, so 13 heats, I would also like to see a British Speedway GP2 Series run alongside it, featuring 8 of the best domestic riders in this category, each rider taking 4 rides over 8 heats with the top 4 riders going into a final, so 9 heats, overall thats 22 heats of Speedway across two different series.

British Speedway GP2 Championship
Try and do what the darts do with betting partners for each of the 8 rounds, generate some prize money to, funnily enough, reward British riders, and have this as a focal point, you are most likely going to get a "new" fan attend a one-off meeting especially if its promoted as a championship round or a grand prix, then its all about trying to then get them to a league match
League Speedway should still exist with just two leagues, the top league should consist of 8 sides, the 2nd league to consist of 10 sides, no cups or pairs etc. just league racing once at home, once away with play off matches, however the below will see the state of Speedway in this country

This could be roughly what an 8-team league looks like with 7 riders, this includes 12 new or returning riders with the number 7's doubling down, If riders don't return then the product gets watered down
The 2nd Division could look something like this, based on only the "rising star" doubling down

As you can see the quality of the league drops significantly and this includes any current NL rider that has an average above 6, you could add more from the NL to make up the numbers or increase who can double down, or try and see what riders might come and race over here potentially young Australians, danes and germans
These riders could earn team spots
The only issue faced is that fans of these clubs won't accept this kind of quality field, but will moan about Guests, doubling up/down and so fourth.
But it does give Credibility, obviously the sides in Div 2 could/should/would run 2nd half meetings which in theory replaces the NDL and there would always be some form of amateur or development league where some of these riders will double down for more track time etc.
