User Access to the feature Subscription lists & Landing Pages

It is important for a AJO user to be able to create both subscription lists and landing pages on there own. Today this feature is connected to a "high level" of user access, like site admin or site owner. In our daily work it is then difficult to test and use this where nice feature because it it not accessible. Could it be an idea to separate this accesses from the high level access that we need today to be able to use this feature. Then admin can keep there admin and owner rights and we can still use this feature when and as we like.
