Movement to Reforge the SPA

With the state of things in America and the world at large, it feels more and more like the dsa, and the American left in general, need to coordinate on a much grander level than we have done in decades. Too many tendencies spread across too many organizations that divides the working class and progressive movements. Has any thought been given to reaching out to other groups like the spusa, sdusa, psl, cpusa, and unions and convening a congress to see if any would be open to reforging the Socialist Party of America? I know this sounds idealistic and foolish. Perhaps it is. But it is an option that should be on the table to unite the American left to fight back against what is coming with Musk and his fellow techno-feudalists. One big tent party, of many strains of leftest thought, alongside a strong parallel alliance of labor unions, to get the message across and, if need be, bring the economy to its knees through sabatoge and general strike. Please be honest and tell me why this wouldn’t work now so I learn the ropes.
