Tips on this idea ?

I really like the Chromatic series, I have purchased some already.
Thinking about making a stand alone set from mainly chromatic modules.
But I have some uncertainties regarding this composition.

1) I have a feeling I can not put the Percal to its full potential .
2) there are 2 modules I am not sure enough to have 2 copies: Ataxia and Euphoria

Do you have any thoughts on that ?
