The answer is no, I just managed to create a class with 128 fields  
using the following:
#set($c = $xwiki.getClass("Sandbox.AttemptClass"))
class is $c
#foreach($x in [1..10])
$c.getXWikiClass().addTextAreaField("xxx$x", "xxx $x", 40,5)
#end

and I suppose that if no-one comes with a better solution, I'll use  
these methods to create my class-anew.
Fiddling with internals always has its dangers.
