I’ve never done it, but it certainly seems possible. If you search for “head rests” on Ebay under “Vintage Car & Truck Parts”, there are dozens of styles that would seem to be somewhat easy to adapt.

Back in the 1960’s Cal Custom even offered accessory bolt on head rests. They were metalflake vinyl cylinder shaped items that screwed to the back of the seat. Unfortunately I can’t find any pictures of them. They were offered in the same variety of colors as the steering wheels of the day. Being metalflake vinyl, I imagine they were hot and sticky if leaned against, but might look interesting today.
