you cant go like asking this without knowing what you are even asking. first you need to know what buddha referred as rupas, rupaskandas, rupa-upadanaskandas... you cant go mixandmatch, they are not that trivial.
what do you exclude?
aha...can we count on us the same or should we go along traditional less risky way?
you tell me, you are the one talking about datu levels of panchaskandas

eye = eyebase (rupa, not rupa skanda) + external rupa (not rupa skanda) + chakku vinnana...
patipada translates to a practical method/path of training.
remember this is the 4th requirement to attain sovan

im not saying nothing. you need to understand why rupa (as skandas) not used in those rupa+chakku =chakku vinnana ... once you understood you will see the issue you say about datu level of panchaskanda...
