How to change Etienne to be decent late game

Etienne for me is in a few ways similar to Quincy, good in early/mid game but falls off hard past r80/100.

Even though Etienne is probably the current worst hero in the game, I've come up with some ideas to give my favourite hero a chance.

Idea 1: Advanced Intel

As the name suggests, I feel that at a high level, Etienne should be able to use the range of other towers to increase its own range, similar to the 200 sub. I think this would help as it would allow Etienne to be placed in a less optimal position for other towers, whilst also getting the same amount of damage with the drones.

Idea 2: UCAV Buffs

Although Perma-UCAV can help with defense, it doesn't do much outside of when the ability is used. Allowing UCAV at level 20 to be able to hit all bloon types by default (can't hit ddts without ability) would be useful for options against ddts in the low 100s as well. Another idea could be to allow UCAV to have multi targeting when a targeting option other than "first" is chosen, allowing it to synergise well with my third idea.

Idea 3: UCAV Knockback

Etienne doesn't have many support options other than global camo detection, so a good addition could be to add a small amount of knockback to the UCAV. Having knockback similar to the 001 super monkey could allow for an additional use due to the high attack speed and the previous idea of multi targeting.

Do you have any other ideas for Etienne buffs? I feel like there are many opportunities but not many executed in a good way.
