Ward system remake possible?

I have simply qeustion - would'nt be nice, if you could downgrade a time of enemy wards whenever you hit it? Now wards have 3hp, that means, if you hit once, you could steal some time of vision. I think, that could be possible, because wards have 60/120/180s.

For example - you place a ward (trinket) and enemy hit it, so your ward now have 45s instead of 60, if get second hit too, time is only 30s. Same goes for other, like 120s - after 1st hit 90s, after 2nd hit 60s. And here for 180s - 1st hit 135s, 2nd hit only 90s.

I don't know, if some1 wrote this before me, i'm sorry for spam. :)
