[O] limit orgmode re-use of header faces after 8 levels?

[Xebar Saram]

Hi all

I use a emacs theme (leuven-theme.el) that has nice faces for 8 levels of
org headers (ol1--ol8).
I was wondering if there was a way to make org not start over and use ol1
face when the 9th level is reached but rather skip to the ol2 face (or any
other level).
is that possible at all?

best
