What if tower damage (to champions) scaled with how much health they have?

Right now towers can feel lacklustre in early lane phase sometimes, as many people can just towerdive you if they get a small lead.

So, what if your opponent needed to reduce the towers hp before it was safe to dive you? This puts a barrier on the laner who just got a kill and is now pushing you under tower, while still allowing a more telegraphed five to be viable.

I propose, In this hypothetical yet not improbable scenario, towers dealt 150% damage when at full health that scales down to 100% and 50% at 50% and 0% hp respectively.

In reality this makes tower dives on someone who defends their tower well much more difficult, but also allows people to take weaker towers with less fear of enemy retaliation.

Thoughts?
