I am not sure whether your question is

(a) what is the proper notation for substitution on the pedalboard? or
(b) how do I code Lilypond?

Nomenclature (general practice):

	^ = toe, above note = right, below note = left
	u or o (little "oh") = heel, above note = right, below note = left

Note 1: I prefer the notation which places all pedal marks above the  
staff refer to the right foot (above = right); all marks below the  
staff refer to the left foot (below = left).
Note 2: there is variation in published music. Sometime v is used for  
toe instead of ^; likewise, o, u, or "n" (an inverted u) is used for  
heel. (Sorry, I am not sure how to insert the correct symbols into an  
email, so I am using the letters u (you), v (vee) and n (en) as  
substitutes.
Note 3: I disagree with the notation illustrated in the 2.10 Lilypond  
manual where "right" and "left" are indicated by the orientation of the  
pedal marks. Here is a reference:  
http://lilypond.org/doc/v2.10/Documentation/user/lilypond/ 
Articulations#Articulations
Note 4: My organ notation reference is "A practical guide to playing  
the organ" by Anne Marsden Thomas published by Cramer Music, Englanad.  
This is an excellent book.

Notation Solutions:

If (a), there are two kinds of substitution:

	(a1) toe to heel or heel to toe on the SAME foot

		write "^/u" or "u/^" using the proper lilypond code

That is: use a slash to indicate the substitution (slash =  
substitution). If you accept the pedal notation listed in the Lilypond  
manual (where "orientation of the symbol indicates the foot", this  
approach will cover all substitutions.

	(a2) toe to toe (heel, etc) on DIFFERENT feet

Conceptually the notation for foot substitution is straight forward.  
Place the starting notation, say ^, above the note. Place the ending  
notation, say ^, below the staff and displaced to the right. Connect  
the two pedal marks with a diagonal line (sort of like a gliss line)  
through the staff from the upper pedal mark to the lower pedal mark.  
Here is vaguely what the result should look like:

          ^
______\__________
_______\_________
________\________
_________\_______
__________\______
                      ^

I've never coded anything like this in lilypond, so someone else will  
have to suggest the correct code for the diagonal line.

All organ notation from Thomas: Practical Guide: sections 7.6, 7.9.3.1  
and 7.9.3.2.

Hope this helps.
