An update on this : after carefully reading the whole post https://hashcat.net/forum/thread-3665-post-20935.html the method of colliding the passwords DOES work with SHA1 + RC4, but only if the RC4 key is of 40 bits length.
It is the case for $oldoffice $1 $2 and $3, but not $4 (the type of my document), which uses a 128 bits length.
