Una versione di ArsClassica “geneticamente modificata”

Ciao a tutti.

Sto lavorando a una modifica del pacchetto ArsClassica. Non dico che la userò per il mio pacchetto: è solo un esperimento che vorrei fare (e che mi sarebbe utilissimo per il lavoro che sto scrivendo).

Questo è il main:
`\documentclass[10pt,a4paper,twoside,openright,titlepage,fleqn,%
headinclude,footinclude,BCOR5mm,%
numbers=noenddot,cleardoublepage=empty,%
tablecaptionabove,abstracton]{scrreprt}

\usepackage[dvipsnames]{xcolor}
\usepackage[eulerchapternumbers,pdfspacing,parts]{classicthesis}
\usepackage{caption}
\usepackage{myars}
\usepackage{bookmark}
\usepackage{lipsum}

\begin{document}
\chapter{Prova}
\lipsum
\lipsum
\end{document}`
Questo è myars.sty:
`\renewcommand{\sfdefault}{iwona}

Che cosa voglio fare?

1. “Semplicemente”, abbassare il numero del capitolo di una quantità e metterlo nella posizione di suftesi, ovvero degli Elementi di Bringhurst. Insomma, lo vorrei più in basso.

2. Cominciare il titolo esattamente dei capitoli in cima alla pagina, senza alcuno spazio bianco prima.

Mi aiutate?

Grazie anticipate,
L.
