look ext_tables.php of th_specialelements.
If you define own content type, you can set fields, how you want.
In fact if you need replacement for text or text with images,
alter ext_tables of th_specialelements.

Endeed you should alter the XCLASS.
I made into an evaluation version tm_contentaccessa, which use hook 
instead and that it fully compatible with newest versions of Typo3.
