Can a homonculus be given class levels ?

I found that thread and wondered if it would be possible to give a homunculus levels in swashbuckler instead of its Racial HD from adding 2k gold... haven't had a chance to look much into specialty stuff for them so if anyone know of any pathfinder companion books that deal with them or add more construct stuff I would gladly look at them.

If you are a DM you can do whatever you want but guessing you are a player, so ask your DM.

As far as I know, you can't add class levels. This is probably due to the fact that class levels tend to be much more powerful than simple Hit Dice, and taking the example of Timmy you'd get a character with the potential to add multiple 9th-level casting.

You can't *craft* class levels into something. Class levels are gained by experience, not from race or HD. Even creatures that cast spells "as X class" do not actually have that class (unless they gain experience and gain a level in it).

DM can allow whatever of course.
