I'd scrap accadamies and invest money into school footballs. Youth football is dominated by school system and then there is a draft like they have in america. Where draft picks are designated based on league position. Teams currently have to help fund the scheme with government. Teams can negotiate draft picks so means smaller clubs will get revenue from those who can afford it.

Cap the leagues at 108 with no relegation out of the league
20 - 1 pl
22 - 2
22 - 3
22 & 22 - 4( North and South)
4 teams relegated from every league and promoted

Massively reduce the gap between TV money between each leagues.

Liverpool got 174.6
Norwich got. 94.5 and the season before in championship got 7.1

I would still reward those performing better but not to that extent.

Every club must record a profit or face 10 point deduction. With profit sharing suggested from club profits.

Scrap efl Cup. Keep league Cup for those not in Europe.

Squads limited to 25 players over 21. If not in the squad player can leave for another club. Stop massive hoarding of players and loan fees.
