arrangement that could be played on piano or acoustic guitar

My son is getting married, and he would like the guests to walk in to an instrumental version of the Pain Remains Trilogy by Lorna Shore. This being Death Metal, it's hardly appropriate for a wedding, but it is very meaningful to the couple, so they'd like an arrangement that could be played on piano or acoustic guitar. I'd like to surprise him, and he loathes AI. What can we do here?
