At least the OP isn't asking that players initially can only play as US, UK, USSR, Germany, and Japan, with all other countries locked off and sold as (possibly day-one) DLC. Total ick.
Sorry for the non-sequitur, but I honestly have no idea what the OP means in terms of movement, aside from eliminating provinces which would completely impede the notion of development, infrastructure, industry, supply, etc on a province level.
He wants units to move anywhere they want(like in a RTS, for example age of empires unit movement, where soldiers represent divisions and the map is the world. Bad example, but freedom of movement that is not locked to provinces. Actually better example is total war Strategy map), and maybe even to choose 'density'(for example, dragging a division over a 100 km front with little depth or over 20 km front but with more effectiveness, like you can in total war battle map). Currently, divisions are inside a single province, with arrows indicating their movement, but those arrows mean nothing. I don't see why removing development from provinces would be necessary. Sure, there is a question of what happens to province production if you are duking it out in the middle of the province, but it's fairly irrelevant in this discussion...
