categories - WordPress - how to overcome category and page permalink clashes -

in wordpress, have category , subcategory:

donkey (slug=donkey-category)    reports (slug=reports - parent category donkey-category) 

i have page:

donkey (slug=donkey, categorised donkey-category) 

and have series of posts:

my post name 1 (categorised donkey-category , reports) post name 2 (categorised donkey-category , reports) etc. 

i want page have permalink /donkey

i want category index page have permalink /donkey/reports

i want each of posts have permalink /donkey/reports/my-post-name-1, etc.

but because page called "donkey" , parent categories called "donkey" having give 1 of them different slug , either compromises permalink page or category , posts.

i have configured permalink custom structure: /%category%/%postname%/

and have "remove category url" plugin (to avoid /category/donkey-category verbosity)
