I honestly don't know how mixed ancestry and the difficulty of producing actuary tables actually affects whether a system can function. Statistically, over a population of that size, it is a wash and the worse that can happen, is that there would be a procentual change in the overall cost. Furthermore, the French have had a mixed populace for many decades [1] and their system still works (though it is different than that of the Czech Republic and Germany). The Czech Republic places 33rd by life expectancy, behind the US by just half a year [2], so if the health care in Czechia is on the level of a 3rd world country than so is the US'.
