It's very much possible if money isn't (or only partially) returned to the companies and used for targeted investment benefiting the public. Of course this won't help much if government spending priories and legislative objectives aren't revised, but that's unlikely because there's nobody in government or academia with anything close to a good idea about it.
Otherwise it’s the same as just leaving the illegal tax in effect.
The SCOTUS didn't say that in their decision. No matter how you call it, the tariffs were found in breach with simple law passed by Congress - that is, the undoing of tariffs can be legislated by Congress and it can take any shape they like - it will be legal. Anyway, fine-tuning this is a waste of time, the big problems are elsewhere.
But we all know they are actually the party of unsustainable debt (with the political agenda of it blowing up the country as they lay out in their 40+ years of starve the beast policy). They then come to threads like this and talk about...the unsustainable debt that their 40+ years of policymaking has created and how government doesn't work (because of their 40+ years of policy making) and we need to get rid of it. 40+ years of destroying the country via starve the beast policy and placing the country in unsustainable financial peril all for a political agenda they can't reach any other way.
They should be well aware of what extortion is.
If Trump did it on his own that's one thing if not it's a conspiracy.
