Sounds like an interesting project.
I recall a few years ago we were meant to be doing something with the CWGC, but I don’t think anything ever came of it.
Lack of interest from previous Comdt AC, but nothing new there 
this was either in 2014 or 2018 in recognition of the start or end of WWI there was a campaign by the CWGC to engage with the youth to have a student “sponsor” a grave - basically to find out about the individual and “maintain” (one off clean) their gravestone in the local CWGC cemetery.
With my RBL hat on i found out about it, but only as far as the publicity that they were going to do it…never seen anything about anyone actually doing it!
edit: ah no, @MikeJenvey proven me wrong…i am thinking about something else
