WP Plugin idea: Only activate plugins that are needed in wp-admin

We use a lot of plugins and unfortunately can't remove more of them. Our backend is slow.

Wordpress is built to load each plugin in the wp-admin backend. So event if you are on the overview on the pages, where no plugin would be needed, woocommerce, contact form 7 etc. will be loaded. They put their CSS in the page but also do PHP stuff and slow everything down.

Is there already a plugin or a hand crafted solution to select which plugins should be deactivated/activated on with wp-admin pages?

The plugins have to be loaded to build the menu - but maybe the menu could be cached. And than only activate heavy plugins on certain pages or something?

Do you know of existing solutions to lower the time needed to build the backend. Are there any caching options?
