His average could be expected to shoot up by over a point = good guest options

Championship will last a couple years max if premiership doesn’t run. People need to realise it’s in everyone’s best interest to have two leagues. 

Your last paragraph is bang on. Making a Championship club take a bullet isn’t the way to achieve it. More clubs can sustain the lower level of racing. Evidenced by the Championship containing more tracks. The way to serve the sport as a whole is to bring the standard to the level that is sustainable across the board. The issue then becomes that because of the mismanagement of the last X amount of years we now have a shortfall of Championship standard riders (let alone Premiership). Not to mention stadium rent costs only going in one direction.  Basically we’re in a huge mess. The solution needs to help as many tracks as possible survive in the short term and thrive in the long term, not just be a vehicle for Ipswich to be able to retain Doyle and Sayfutdinov. 

So what?  Only one team can win a title -- real success is having an entertaining team providing excitement for fans, getting enough bums on seats to pay the bills.

Neither a title winning side

They have two solutions.. 1. Run a "Super League" with (five or maybe six?) teams at last years tier one level and hope they get some TV coverage.  With those teams then running a 2nd team in a league that matches a cross between last years Championship and NDL levels, with rider/average controls in place to share out the HL's.  Or 2. No GP or Polish contracted riders at all and just running one league at a Championship/NDL level running on any nights the clubs want to, to maximise crowds, with some kind of average/rider control to share around the HL's... Let's face facts. . Bringing back the GP/Top stars simply hasn't worked across the league, as fans are now able to watch them ride in Sweden on Tuesday, Poland on  Friday and Sunday, and in the GP's, Euro Championships, SON, SWC etc virtually every week of the season... With several visits to your own track during the year, any "novelty" has now long gone and their presence simply hasn't added the numbers to the atrendances that was obviously hoped for, and intended, to do.. Ipswich fans may say different, however, when they travelled away "huge crowds" didn't pay to watch Emil and Doyle and even at home in the many POQ "dead rubbers" their crowds, whilst better than anyone elses, were hardly "bumper".  Contrast and compare Emil's first season to his last away from home. It became just another Speedway meeting, where, in his first year there was some "box office" to his arrival at your track.. The Aces had some very low crowds with two of the top 3 riders in the world, (being two of the most exciting riders too), riding for them... I would say the lack of jeopardy and repetition of visitors, in so many meetings, keep more fans away than the GP riders can attract, especially as they are only "big names" in a tiny, tiny pond, so hardly anyone outside the small number of followers of the sport, in fhe UK, could even name them.. One league will at least bring some different teams to tracks, which may stimulate some "novelty value" at least.... Granted, it's a low bar, but the current operating model clearly doesn't work...
