Oh, come on. This is too simple. 
You can already create easily any kind of inherited component. Just
close the designer form and change the ancestor in the source. The only
missing thing is a dialog, that do this in on step.
I already wondered why you didn't provide a dialog yourself. You wrote
the project templates, so I know you are skilled.

Anyway, here is "the essence":
I found a nice patch for this in bug 1287. I simplified and extended it
and now you can inherit forms, datamodules, frames and custom component
classes via the new dialog.

Lazarians are spoiled.
