US ground troops in CBI

Not to detract from the 60th anniversary of D-Day, but what would've been the effect of the US deciding to commit much larger nos. of troops (ie at least an entire combat div) to the CBI theatre during 1943/44, in addition to providing the logistical and air support OTL ? WI US inf divs which had been trained for combat, but OTL were never deployed overseas (such as the 39th DELTA Div, comprising NG outfits from the Mississippi Delta states, or the 55th PANHANDLERS from California), had been deployed into combat under Stilwell's command in Burma, alongside the British 14th Army and in addition to the USAAF Air Commando, the 'Flying Tigers', engineering/construction and transport units (many of whom comprised African-American service troops), the 5307th Provisional Unit/MERRILL'S MARAUDERS, and OSS Detachment 101 with their Kachin scouts, who were in action ? How much would US influence in CBI have been enhanced and the postwar strategic situation affected ? Could a greater US influence in CBI have led to such changes as definitely persuading the Brits to make good on such postwar promises as the guarantee to grant the hilltribes such as the Kachin and Karen their own separate homeland (which OTL have never eventuated and still underpins continued civil war between these groups and the Burmese/Myanmar central govt) ?
Melvin, my understanding is the US deployed all the units it could overseas during WW2. They were limited by transport as much as anything else, and at the end of the war in Europe had only the equivalent of about 3 divisions at home - the rest having been broken up for re-inforcements etc. That being the case, where would the troops have come from?
