Hungary PODs during mid-19th C

after viewing the wiki article on Lajos kossuth, the following PODs spring to mind:
WI Kossuth, after fleeing to the US in 1851, stays on there after 1860 & ends up playing some prominent role in the ACW ? Perhaps becoming 1 of the foreign generals a la Franz Sigel organising foreign volunteers for the Union ?

WI some of the other Hungarian generals such as Artur Gorgey also find their way over to the US & fight for the Union during the ACW ?

WI the Hungarian Legion proposed by Kossuth to fight in the Crimean War became a reality, & served alongside the Brits, French, Ottomans & Piedmontese ? Could the presence of a Hungarian force in the Crimea have facilitated Napoleon III's later direct support for Hungary in the same way as occurred in 1859 for Piedmont-Sardinia due to Victor-Emmanuel's dispatch of his expeditionary force ?
