To clarify my amendment proposal

Aronsons swapper has two moves..

Positional swap 
P(S,P)=>(P,S)

Mutual destruction
M(S,P)=>(_,_)

I recommend removing the latter, which seems to refer to a separate concept, and adding 2 new swap moves.

Colour swap
C(S,P')=>(S',P)

Type swap
T(S,P')=>(P,S')

The fact that this is a natural completion of the concept can be shown from the fact that any swap move acts as a combination of the other two (for friendly pieces T and P are equivalent, and C is a null move).

The resulting piece is considerably stronger (probably the equal of any piece on the board), more logically consistent, and I would argue no less intuitive or complicated than the current version or some of the proposals.
