I managed to stick a 255 lph Walbro in my fuel tank using a kit for a '94-'97 Mazda Miata, of all things. Only modification to the tank was running the wires through the sending unit.

How about some sort of sump/baffle system to allow running the tank below 1/4?

Haven't really figured out that yey. Mine has fuel starvation issues when cornering with a low tank.

And if someone's done this, is a behind-the-seat in-tank pump really quieter and more reliable than an external pump?

Unsure on the reliability part, but you've got a fuel pump sitting right behind your back. It's pretty noisy.
All in all, I've found that putting a fuel pump in the stock tank was an interesting exercise to see if it could be done and see how easy it is to put a high pressure pump in a carbed tank, but would be a better mod for something that had the fuel tank underneath.
