don't think this will work
the main problem with the item is that it's active is generally useless.
compared to
for example, i could write a 20 page essay on all it's uses it's unbelievable what you can do with that items active. use it as a portable wall, use it to make wall wider and spam ctrl+4 as your enemy wallflashes, an extra ward on demand, the minions give vision too so put it near blue buff and see them take a detour to midlane giving vision of your jungle a part of river and the sidebush of midlane
use it to defend vs sieges, use it to siege yourself. use it to afk push a wave.
There are so many many more uses for it, it is crazy.
Is it always reliable yea sort of not in all it's uses sometimes you can manage to waste it but this is offset by it's sheer versatility
then there are other item actives like the shielding items
they are always good and reliable in any situation where you are about to take damage, whether that's team fighting, tower dive or defending, blocking poke it's always good and it's super reliable and it scales nicely balanced into lategame.
active reverse scales, it get progressively less useful as the game goes on. you can buy
to gain extra defense and damage or ohm wrecker. Either way the defensive stats alone will allow you to towerdive anyway. so in a sense the item already works against itself, though with it you can now do an extended towerdive which you will need because you didn't gain damage like you would from sunfire cape
Then as the game progresses there will be less and less towers to disable untill the active is essentially worthless less towers makes it less usable and more tank stats make it less needed.
If the active had more uses like zapping an enemy champion to ground them and reduce their damage output, basically making them more vulnerable then it would stay good throughout the game.
If it in addition to zapping an enemy champion it could also be used to buff your own turret like giving it a shield + splash damage as long as that shield persists then you got yourself a wonderful usefull item active which doesn't become progressively more useless as the game goes on.
It's stats are ok tbh
