Weird SOC, but can it be done?

[Fish hook]

I'm making a shark character and the first bit of his SOC is done, the ability to breath underwater, but this semmed unfair to other players if used in match mode. So I thought if it was possible to SOC the drown timer for dry land. Heres how I would like it to work.
You can stay on dry land for 5 minutes, then die.
If you go underwater, your 5 minutes on dry land gets reset (Like when you go to the surface as a normal sonic character).
He can move faster underwater that on dry land.
So is any of this possible?

Probably not. You can turn the timer off in water, but you can't really turn it on in land without use of an EXE that gives your shark an SPMove. (but, I persume that term is copyright of JTE)

Would it be posible to SOC every level to have the same properties as space and use the spacetics thing, but it only activates when you play as Scar.
How do you make a SOC only work for one character? The Underwatertics effects all the characters, but I only want Scar to breath underwater.
