I did it and I have no regrets.
My priorities for the build were reliability and low maintenance. No carbs to adjust, no timing to adjust, no points to adjust, just smooth reliable efi power. I don't even need to adjust valves for another 100k miles, just put oil and gas in it, that's it. I only open the decklid to show off the swap. I can leave it closed and it's an aircooled-look vw haha. Except it doesn't leak oil.
I can assure you that it does not take the soul out of the vehicle. My bus still rattles, squeaks, whistles at speed, has that old VW smell, random interior parts break from time to time, steering is more of a gesture than a command, and all the kids take pictures of it when I park it at the burger stand. It's the look and feel of the bus that gives it it's soul, not the engine powering it. At least in my opinion.
I completely understand the emotional attachment to the OG aircooled engines. I used to feel that way too, until I rode in a swapped vw.
Try it... you'll like it.
