How to modify this Biblatex style?

Question

In this useful post, I asked how to use biblatex's verbose. Now, I'd like to customize a little this style as follows:

1. Just after the name of the town, there should be a comma instead of a colon.
2. There shouldn't be apostroph for an article title.
3. The name of the journal mustn't be preceeded by the mention "In".

In a nutshell, any trick to customize this verbose style? This is my MWE:

\documentclass[12pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage[backend=biber, style=verbose]{biblatex}
\usepackage{hyperref}
\DeclareDelimFormat[bib]{nametitledelim}{\addcomma\space}
\begin{filecontents}{\jobname.bib}
@book{Winnicott1975,
  address   = {Paris},
  author    = {Winnicott, Donald Woods},
  publisher = {Éditions Gallimard},
  title     = {Jeu et réalité},
  subtitle  = {L'espace potentiel},
  year      = {1975},
}
@Article{Chiantaretto2005,
author = {Chiantaretto, Jean-François}, 
title = {À propos de la première transgression}, 
journal = {Topique}, 
volume = {92}, 
number = {3}, 
pages = {111--125}, 
year = {2005}, 
}
\end{filecontents}
\addbibresource{\jobname.bib}
