Sadly, not (sanely) with a Norwegian keyboard layout. We "only" have one key left of z, namely "<" (and with shift ">") -- and not really any keys right of "l" and "p" -- right home-row is "jklø" followed by "æ", and "å" is right of "p".
Way out in the cold by the enter key we have "'" (shift for "*"), and the not-so-useful composing '"' (and "^~" with shift/alt-gr respectively).
If only we could stick to something like romaji'zed Japaneze, we'd have plenty of keys left over! ;-)
I tried it for a couple of days, maybe not long enough, and I guess a lot of this comes down to feel, which comes down to previous typing experience and personal preference, which seems that it may be highly personal (though I don't have data to back that up).
