Umm...you mean without writing to any extra memory, or without using any registers to do it? And I'm sure whatever method of doing it probably just involves using the registers to move the data anyway. You could just move it a word at a time, holding the swap value in AX, the current position/offset of each location in BX and DX, and then use CX as a counter to go as long as you need it.
