base pages without kludge initialization

Everyone,

Let's say I want to make a base page, extending WebPage. I want to make
it flexible so that subpages may initialize either using a model or page
parameters. So I try to do this:

protected BasePage()

this(null, null);

protected BasePage(final IModel<?> model)

this(null, model);

protected BasePage(final PageParameters parameters)

this(parameters, null);

private BasePage(final PageParameters parameters, IModel<?> model)

super(null, model);
//initialize stuff here

Obviously I can't do this, because several of the WebPage (and ancestor)
constructors are marked private. I'm forced to do this:

protected BasePage()

super();
//initialize stuff here

protected BasePage(final IModel<?> model)

super(model);
//initialize stuff here

protected BasePage(final PageParameters parameters)

super(parameters);
//initialize stuff here

private BasePage(final PageParameters parameters, IModel<?> model)

super(parameters, model);
//initialize stuff here

Look at all the duplicated initialization code! Sure, I could create a
local initialize() method that each of the methods delegate to, but not
only is that ugly it prevents me from making my class variables final
(because final variable must be initialized in the constructor).

Couldn't the parent classes be a little more lenient, allowing access to
all the constructors, making child classes meant to be base pages more
elegant?
