This is a possibly slightly bizarre question. I am aware icons are generally not displayed at graves and this is not something that should be done. However I have received mixed feedback on whether or not a copy of an icon engraved in stone or as an etching can be displayed. I have a particular icon of St. Patrick in mind to place on a family headstone underneath the text with him holding as scroll containing the opening line to St. Patrick's breastplate. I do not wish however to annoy anyone and as the cemetery contains a number of Eastern Catholic graves nearby and also some Orthodox ones* I don't want to aggravate anyone.
*Yes I know Orthodox are not meant to be buried in Catholic cemeteries but the cost of a grave in London is fantastically high and at present numerous Orthodox Churches quietly turn a blind eye to the matter as otherwise those seeking a grave simply could not afford one. My family plot would cost around a minimum of 7,000 to 8,000 dollars per person if I had to buy it. Fortunately, very fortunately it was a present gifted to my late mother.
I don't know of any canonical or theological reason that would prohibit the idea you propose. On the contrary, it sounds like a very beautiful idea!
