The most simple thign anet should do here is putting an NPc to the game, that turns your skill points into Scrolls of Expericen and that together with a gold/karma fee to create the scrolls fro you.
These scrolsl are then account bound and can be given to any character of your account and the character which uses this scroll, will receive the Exp and Skill points.
Example: (only useable if you have at least 1 lvl 80 character on the account as the npc talks only with max leveld characters)
Scroll of Shared Experience: Costs 30 Skill Points, 5 Gold and 50000 Karma.
Creates a Scroll of Shared Experience, that will boost a Character up by 20 Levels and give the Character 20 Skills Points
Scroll of Shared Major Experience: Costs 50 Skill Points, 10 Gold and 75000 Karma
Creases a Scroll of Shared Major Experience, that will boost a Character to up by 40 Levels and give the Character 40 Skills Points
Scroll of Shared Superior Experience: Costs 70 Skills Points, Costs 15 Gold, 100000 Karma. Creates a Scroll of Shared Superior Experience, that will boost a Character up by 60 Levels and give the Character 60 Skills Points
With that way would be a player able to raise up quicker twinks if you have enough money, karma and skill points on your main and you know not wherefore to use them up, it would be a way and it would take money/karma out of the game as a direct money/karma sink.
And therefore that ypou build up quickly a twink, you’ll lose also some skill points extra as part of the fee to create the scroll.

However, I hope that Anet introduces hopefully soon more new utility skills, more elite skills and new healing skills to spend our collected skill points for what they EXIST mainly for!
For unlocking new skills with them.
Personally I like the idea behind sub classes ~ quoted from Chris Whiteside
