There is a way in multiplayer games. Just export a char from the savegame of your choice and let him join the MPgame with all the equipment.
There's also a cheat if you want to get the equipment right at the beginning (or want to keep your equipment from BG1 for example).
Press Spacebar immediately at the beginning of the game (at the black screen before you hear any sound). Then bring up the controls with "H" and drop all of your equipment (which you haven't lost yet) on the floor. This way the game won't erase it when "clearing" your inventory.
If you really want to swap items from one SINGLE Player Savegame to another there is positively no other way than CLUA or Shadowkeeper.
