Everything is possible with code! :-)
But, to be more precise, yes, you can contribute any number of 'advice'
particles to an element-type to configure new instances with as complex
a structure as you need.
By "instances", do you mean specifically "instance specifications" as
modeled in UML? If so, I would suggest that the classes for which they
model instances should rather be in a library model than in a profile.
The classes in a profile are really only intended to be used as types
for the attributes of stereotypes, as complex extensions of the UML
metamodel. Putting model elements in a profile that should be
referenced by instance specifications or anything else in a normal
"user model" would be mixing meta-levels in a confusing way.

First, I should comment that you could hardly be misusing UML: the UML
is intentionally designed to be useful for every conceivable purpose.
(I may just be kidding)
Library models are probably best used as repositories for
domain-specific concepts that need to be referenced by the users'
models. For example, they might contain classes that are intended as
the types of properties of the user's own classes or as generals of the
user's classes. (libraries can contain anything else than classes, of
course; this is just an obvious example)
To register a library model for use in the import dialog, just add an
extension on the org.eclipse.papyrus.uml.extensionpoints.UMLLibrary
point. It's very like registering a profile, which I think you have
As far as the palette is concerned, yes it is naturally going to be a
good deal more complex than what you can do with the palette
customization tools provided out-of-the-box by Papyrus. You have used
post-actions to apply stereotypes to new model elements. The GMF
Run-time's "Element Types" framework implements a generalization of the
concept of the post-action, called "advice" on the
CreateElementRequest, that lets you attach arbitrary code to the
creation of a new element. Open the AbstractEditHelperAdvice class in
the JDT's Hierarchy view to see several examples in Papyrus of these
kinds of advices. Some of them I am sure will advise the creation of
new elements and hopefully provide a guide for your situation.
