One really broken card is all it would take to fix anything if you're willing to go far enough.
Realistically though Toons should have a complete overhaul. Their gameplan is extremely uninteractive because all it is is
>every toon monster is basically a towers as long as you keep up Kingdom
>also they attack directly so if you don't out them ASAP they will just kill you
The problem is that that gameplan is accurate to the manga where it was one of the most iconic duels so turning the deck into a regular interuption based board-building strategy would be utterly sovlless.
Toons do have some really powerful cards though. Table of Contents, Bookmark, Toon DM, etc so any Toon Circular would instantly boost the deck a ton since it'd be very accessible.
If they gave it serious support I'd imagine that it'd be engine improvements that'd let you more reliably build a board and protect it with Toon Terror+Bookmark then OTK on turn 3. It'd be kind of like Melodius. They could also just make it an OTK deck. Some of the current Toons can already attack the turn they're summoned. They can make extra deck Toons too. Toon Dark Paladin or even Accesscode sounds cool.
If they did give it proper quick effects, like a quick effect Comic Hand/Mimicat or maybe just do like Golden Allure Queen does and make their current Toons into quick effects(DM could summon Harpie, BLS could banish, etc) then I think it'd be cool if it came with a mandatory Toon Defense type effect that lets your opponent attack directly as a downside.
