Is it possible to trade stuff to your lower levels?

Without the BB Glitch.

Say I dropped some items somewhere, and switched characters, could I then pick those items up? Would I have to find someone of a lower level to trade them to so they can give them to my other character?

The only way I can think would be BB glitch a level 1 and use it as a mule to give stuff to your lower levels.

I'm looking to start building a pvp build and set him up with some decent low strength equipment, to make the run through Anor Londo/Catacombs and killing 4k much easier.

Or you can just develop your low level equipment. My SL 8 has better equipment than my SL 25 and every bit of it was earned.

The only sucky part is my Drake Sword +(whatever) is my strongest weapon because scaling stats don't help very much at low levels. Upgrade the crossbow to fire for easy distance kills. Stock up on Heavy Bolts.
