I haven't read anything, but I suppose you could open the metafiles:
use MyForm.scx
and then do some REPLACE:
replace class with "cTextBox", classloc with "MyDerivedClasses.vcx";
for lower(class) = "textbox"
Repeat for other base classes. Repeat in a loop for all forms and form classes.
CAUTION:
Make backup first. Replacing metadata can lead to unexpected results sometimes.
