Short Answer: Likely not.
Sharing equipment or special items between game files is increasing common in games, esp games that require to pay for such items (freeium, pay-to-win etc). However, in Exiled Kindgoms the game's balance takes into consideration available equipment and every slight improvement counts. As the poster above points out, starting the game with end-game equipment would really throw things off. Also, EK doesn't require in-game purchases for storage, special items, special equipment or for a special ending so there's no real benefit of sharing stuff between game files, except for the novelty of it and getting an edge on the game.
Besides, the game developer is an old school dungeon master. He likes to make you suffer to get that +1 increase in DPS.
