Synodality: the Legion of Mary as a model?

I am not sure I completely understand the UK's system of public honours, but each time a list of awards is published (typically, the New Years Honours and the Queen's Birthday Honours) I am reminded of the practice of the Legion of Mary, which is that no honours or presents are to be given to members. Instead, when there is some occasion that calls for recognition, a spiritual bouquet (ie a promise of prayers) is offered instead (cf p.303 of my edition of the Legion Handbook). 

In this, as in other things, Frank Duff seems to have been very much ahead of his time. Which prompted me to wonder whether he was also ahead of his time as far as "synodality" was concerned... 

The Legion Handbook (pp.11-12 in my edition) states the object of the Legion as follows - I have added the italics to draw attention to the aspect of "walking together" that is contained in this statement. The dimensions of ecclesial communion, participation and mission are also very apparent.

The object of the Legion of Mary is the glory of God through the holiness of its members developed by prayer and active co-operation, under ecclesiastical guidance, in Mary’s and the Church’s work of crushing the head of the serpent and advancing the reign of Christ. Subject to the approval of the Concilium, and to the restrictions specified in the official handbook of the Legion, the Legion of Mary is at the disposal of the bishop of the diocese and the parish priest for any and every form of social service and Catholic action which these authorities may deem suitable to the legionaries and useful for the welfare of the Church. Legionaries will never engage in any of these services whatsoever in a parish without the sanction of the parish priest or of the Ordinary.

The aspect of "walking together" is most clearly lived out when the (parish) priest spiritual director takes an active interest in the work of a praesidium, attending the weekly meetings and indicating work that might be undertaken. The structure of Legion councils also indicates the dimension of ecclesial communion - the praesidium is part of a Curia; Curiae are part of a Comitium; a Comitium comes under a Regia; and, finally, there is the international governing body of the Concilium. But at each level the role  a spiritual director indicates the "walking together" of the lay legionaries and the ordained ministry.

Participation and mission are reflected in the duty of legionaries to attend a weekly meeting and complete a weekly obligation of a substantive apostolic work (cf pp.191-194 of the Handbook). A key theme, both in the Legion Handbook and in the writings of Frank Duff is that of the necessity of a laity imbued with a vivid apostolic spirit, who work in collaboration with their clergy for the good of Church's mission. 

Is this perhaps the key to Pope Francis' encouragement that we should "walk together" on the synodal pathway?
