Sure, but in the context of the original point - even if we did replace the bourgeois institutions of America with proletarian ones, it would still have significant American characteristics, because it would have to grow out of those bourgeois institutions first. Look at the way that the American bourgeoisie (mostly) carried over English monarchic common law, for example, there would still be things like that. That’s what OP was asking for, and it’s why /u/pppp1000 's comment is so nonsensical.
