Nice idea. I dont usually like the idea of killing palms, but there are plenty of washingtonias in California and they are not easy to transplant so if they are in the way, better to make some use out of them then to just throw them out!

I'd imagine that harvesting the heart of the palm might be a little difficult though, so Im interested in hearing how it goes!

Are they even edible? I know palmettos are called cabbage palms because of their cabbage like taste when the heart is cooked. And the Latins are fond of palmito (heart of palm), which likely is a sabal palm or cousin. Are all palm hearts edible?

It was quite difficult! at least the first one was. I basically took a saw to all the leaves, and sawed the base clear from the roots, ending up with the "body" of the palms (the palms were no more than 8 inches in diameter at the base). Then I peeled off leaf bases until I reached a starchy, white center, which I then salted and boiled. It tasted somewhat like asparagus with a faint hint of corn. Definitely worth exploring new recipes with them!
