I’ve tried this before, but involved a much more expansive change to the turn order. I tried an opening round for most turn orders with G40, for experiments on the variable start to the turn order idea discussed here… http://www.axisandallies.org/forums/index.php?topic=34111.msg1313426#msg1313426 and elsewhere, like with AA50.
Basically if you change the turn order (Whether a set change, or trying to use a system for variable start) its pretty important to introduce some kind of bonus income to compensate for totally jacking up all the first round battles haha.
So for example, one reasonably successful France first turn order we tried was
Italy, France + Russia, Germany, UK + Anzac, Japan, USA + China
but awarding fairly sizable bonuses for things like holding Capitals or VCs, since a lot of TUV trades differently once you alter the order.
another which was interesting but a bit less intuitive was China+France+Anzac, Germany + Italy, UK+Russia, Japan, USA. With more of a 5 position game (And all the lesser powers going at once.) But again, requires starting income adjustment to balance.
All the distortion in turn order changes come from busting naval battles in the first round, so sometimes we used ideas like a restricted opening (e.g. the first player to go, doesn’t get to make combat movements, just non-com and placement.) This is a system that was in use for Classic 3rd edition with the restricted Russian opening. Basically you can try something similar with G40, for other nations, if you want to try experimenting with different possible turn orders.
My favorite way to approach this is not to alter the OOB unit distribution at all. All the same units, in all the same places. Just with a different turn order, a possible restricted opening, and then changes to starting income or income bonuses throughout. That way you don’t have to change a bunch of pieces around, just the order of nations and the money.
So as an example, any sort of game where France goes first is going to require more money to Germany or Axis generally. Any game where Italy goes before UK, is going to require money to UK or Allies generally. Stuff like that. Its not impossible, just a matter of how much additional starting money to award, when you alter the order.
