So my experience with Lucky Islands is that it's very annoying when you're new to the game, you're checking out the cool Lucky Blocks and suddenly you get rushed by someone who already played the game so much that they know every single loot item out of their head.
Adding this kind of kit would just encourage more skilled players to use this strategy. Kits have a weapon, blocks, or some other items that you can use, it's never two of them combined.
If this kit would be added (1 stone sword + 20 stone blocks), it'd be a combination of two kits, making them both useless.
That's why I voted no for this suggestion.
