Proposed summoner spell changes :heal, clarity, and clairvoyance

What if these had passive auras, (or just passives for yourself)? Here's my idea:

Clarity increases base mana regen by 100% passively (or 25-50% base mana regen in a small aura) either one not both.
Heal increases base health regen by 50% passively (or 25% in a small aura) either one not both.

Now clairvoyance.... its, well, stupidly not viable to the point of me never once seeing it used in all my games in history ever (1.5 years isnt long to some of you, but thats a LOT of games where clairvoyance could have made an appearance) , I have never once seen it and for that reason I have no idea why it exists anymore.

Clairvoyance proposed passive 1: you and nearby allies gain bonus movement speed when going towards the area revealed.

Another idea: passively increases your sight range by 100-300 units (ik this would be op but come on clairvoyance is absolutely useless right now).

Or this: clairvoyance now reveals stealthed units and traps

slightly different subject now, since riot has keenly shown with the last patch that they love changing the playstyle of specific groups of champions, what if supports had an item that allowed them to use their summoner spells on an ally? It goes like this, they activate the item, and for a short time they may use one summoner spell on an ally or allow an ally to use the summoner they chose. This would be op but what if it (the items active) mimicked the cd of the summoner spell or doubled it? for balance reasons.
