Hum... is the real issue that you want to move the water heater to the attic? If so, I'd agree with the other poster, do the electric tankless - but it'll not be as efficient.
If the real issue is that you want to (for some reason) replace gas with electric... I'd say, "why?" Is your gas line going away?
I did a bunch of research on using tankless hot water heaters about a year ago. Tankless-gas was the way to go for efficiency, cost reduction, ease of installation. Here in florida, you can install the thing on the OUTside of your house even... if you want to. Or you can zone it, using smaller units for strategic parts of your house (say one unit for kitchen, one for laundry, one for upstairs baths... ).
I wouldn't put a water heater with all it's pipes and such in the attic. Would just be more ceiling, wall and floor to rip out and fix should one of the lines burst or something. If you're in a very cold climate, I'd think that the attic would tend to be a risk of freezing...
???? I'm curious...
