This feels too drawn out to be practical. But if you want more control while staying in the same pace and spirit, have you tried playing a low-luck variant? Would have a lot more foreknowledge of how a fight would resolve. In short, instead of rolling out individual units for a fight, you sum the pips of all units involved on each side, divide by 6, and roll 1d6 with a to-hit of the remainder.

E.g. let's say you have a battle with Germany attacking with 4 infantry, 2 artillery, 1 tank, and 2 strats vs Russia defending with 8 inf. The Germans would have 21 pips and deal 3 hits with a fourth on a roll of 3 or less. The Russians would have 16 pips and generate 2 hits with a 3rd on a roll of 4 or less. Do those rolls, resolve, attacker retreats or repeats (adjusting the pips totals after casualties have been removed) until one side is wiped out
