This would be an amazing boon for achers, that's for sure.
1 slot bow , 2 stacks of arrows, 1 weightless ladder. Deploy the ladder early on and later when melee pushes find a dead guy and take his sword.

2 slot bow, 1 stack arrows, weightless ladder. Hold ladder till midround- deploy in unexpected location near enemy lines. Rain death from relative safety, as an added bonus halfway through the round enemy ranged is thinned so even safer strategy.
Even though this would make my playtime as an archer significantly easier, i think this would horribly unbalance the game and lead to very frustrating situations for melee where every archer was on a rooftop and every melee had to carry a spare ladder.
