Levelling without leaving the continent

[necrosaurio]

OK, so my plans to level with a friend fell out, so it's all solo for me from now on. After my last adventure trying to get through Highpass, I got druid-envy (hey Nagash) and decided to level one. After playing it to level 8 and loving it, I've noticed that there are too many zones to play and too few levels (specially if you count travel time), so I've decided to play a char in each continent, without leaving the continent until level 50, if possible.

The chars are going to be:
- A halfling druid, to be levelled in Faydwer. OK, he started in Antonica but there are lots of half-height drops in there so it made sense to me to get him there. This is my main char [You must be logged in to view images. Log in or Register.]
- A dark elf enchanter, to be levelled in Antonica. Having illusions really helps here, so I can play Freeport.
- An iksar necro, to be levelled in Kunark. I love necros and I love iksars. And it names my account. Shame I deleted my account on a death related rage, so it's restarting from 1 time again.
- An erudite wizard, obviously, in Odus. I prefer gnomes but it makes more sense to play an erudite in Odus.

Despite all the chars being casters, all of them play a different way (the druid will mostly be doing root rotting, just to keep it different).

I am not worried about the levelling and I know it is going to take a long time, specially with my schedule. Also, it will be stupidly hard to pass equipment/money across, being in separate continents with only one char having access to EC, so it's all non-twink work (except for the druid, I managed to buy some equipment, thanks to Nagash again and to the kind druid who gave me a +20mana ring the other day).

My bard (and my ranger) will have to wait until the hybrid penalty is removed. Or, for the bard, until swarm kiting works.

Is this possible or will I hit levels where it is impossible to level up without leaving the continent? Am I completely mad?

Completely unrelated question, how much exp do you get from the orc scalps in Highkeep at level 8? This is for my druid and I might make an exception just to get through to level 9.
