So, you're basically asking for Hoover to be Roosevelt.
I'd believe a 1930 USA Communist Revolution timeline before a Hoover New Deal.
You don't need Hoover to be Roosevelt, you need him to be Harding and for Benjamin Strong to last another two or three years before kicking the bucket
Strong in his role as head of the New York Fed, and first among equals of the Fed, effectively ignored the gold standard in 1922 to stabilize the money supply and continued to stretch the definition of the Gold Standard throughout the 20s to keep prices stable. He may have some responsibility for the severity of the Depression, in that he kept interest rates lower than they would have been so that Europe could recover from WWI better and pay the US back, but by the 1928 he realized he screwed up and raised interest rates and limited credit to try and choke off the bubble. He then died on October 6th 1928 after complications from Diverticulitis, about a year before the Depression
After Strong died the Fed shifted from maintaining price stability, or trying to keep the money supply stable, to a Real Bills Doctrine, where they would only make loans that were backed by paper representing goods in production. As a result at a time when lots of companies and especially banks needed loans, they could not get them as demand for physical goods had dropped, so the Fed was giving out fewer loans to banks. This was made worse by the Fed's "Direct Pressure" initiative, which was meant to punish banks for getting involved in the stock market bubble by not loaning to banks that provided "speculative" loans, and had such a nasty inquisition process for determining whether or not a bank issued "speculative" loans that those who did not still would not get bailed out
So Hoover does like Harding does and lets the Fed do its thing, Strong keeps the Fed lending money to banks, fewer banks fail, more businesses can get loans, and the Great Depression is probably more like 1919-1920
