Is it possible to have a multiclass character in Dungeon World?
Please notice that I mean a real multiclass character, not moves multiclass dabbler and multiclass initiate.
For example, is it possible for a fighter to get thief's Trap Expert, Tricks of the Trade, Backstab, Flexible Morals and Poisoner?
Non-offical materials may be accepted, but they must be something tested. Third party published materials are welcome, especially from RPGNow or DriveThru RPG.
Please remember to note about the source of information.

There are three ways to handle multiclassing outside the Multiclass Dabbler, Initiate, and Master advancement moves: changing to a new class after level 10, creating a new Playbook that incorporates both classes, or creating a compendium class that incorporates the desired multi-class (Thanks to Slow Dog for that reminder).
Leveling Up: After a character progresses past level 10 in their starting class, they have several options. For the purpose of broadening a character's abilities to include those of another class, we want to take the option to Change Class.
Through this process, and with GM approval, the Fighter could potentially keep his Signature Weapon (and maybe his ability to Bend Bars, Lift Gates) while still gaining the benefits of being a Thief.
Creating a New Playbook: As an alternate to taking either Fighter or Thief, players working with their GM can put together a new playbook that incorporates the features they like from both classes. If you are interested in crafting your own class to fit your vision of your character, it's best not to use a class that is already played by someone at the table. The big worry would be that your new playbook steps on someone else's toes. This is the same justification given for why moves like Multiclass Dabbler act as though they were one level lower.
The third way is by use of a Compendium Class. Compendium classes are sets of moves that allow players to add certain advancement options to their playbooks base. Generally, these require some fictional circumstance to justify the gaining of the compendium class, for example
A compendium class that could potentially work for the purposes of giving the Fighter some of the Thief's moves would be:
Again, this method only works if you don't already have a Thief in the group since even a compendium class shouldn't be allowing one character to intrude on another's niche.
