If you can make a composite tank so it comes out easily I guess it would be as good as aluminum. The key issue is being able to take it out to get to things below it like brakes, behind the panel area, behind the firewall area, etc. Getting upside down head first in a KR is damn near impossible and extremely unpleasant. I've thanked the builder of my KR many times for putting in a removable aluminum 17½ gallon header tank.
When I got my plane it reeked of gas fumes but it wasn't the fault of the tank. It was because every single fuel connection was loose and leaking. Once I took the tank off and tightened all connections there have been no fumes. When I started smelling fuel recently I found the brass fuel valve leaking and replaced it. No more fumes. My tank is 23 years old and has had a lot of use. There are indications that it has been repaired at some point, but that was a long time ago and there's been no problems since. Since I damned near killed myself with gas fumes flying my KR back from where I bought it, I'm extremely sensitive to gas fumes and will tolerate none. I highly recommend an aluminum tank. If it's leaking, just fix it! Wrapping it with composite doesn't seem like an optimum solution. As for a composite tank, good luck. Just make sure it's removable.
