[fw-mvc] Zend_View directory layout

I'd like to slightly change the layout of base Zend_View directory layout.
The current layout is as follows:

view
filters
helpers
scripts

... and I'd like to split script directory to several directories(themes),
depending on a theme user will choose.
For example:

view
filters
helpers
scripts
default
modern
classic

What is the best way to shoot the bull?

Thank you,
