Check out the lore and other battle systems sub forums. This thread appears to me you are trying to interview for a job. Compared to what others have fleshed out in minutia, your suggestions are in best cases under-researched. 3 of the 4(5) ideas you provided have already been produced, granted one is an illegal third party app. The other items have been theory crafted beyond minutia.

Not saying you should not pursue this opportunity if you wish, however if you want a free crowdsource to assist, you need to bring more to the table then vague pitches.
