Can Cass E give her a snake like dash when she is out of poisoned target range?

Please read before down voting.

Beside the Medusa theme Cass has, she is also a snake like creature and snakes have very unique movement mechanics.

So here is what I'm suggesting.

If Cass poisons a target, and she is out of her E range but within 1000 range, she gets a snake like dash upon casting E. This dash will put her in range and then go on a cooldown.

This is not an ordinary dash. It is a diving snake like twirling motion that is shaped like an "S" that can allow Cass to dodge skill shots if timed right. It would function like hunt passive where she gets a modified dash.

Another thing that would go a long way in improving Cass is a quality of life buff. Sometimes it is hard to tell if a target is poisoned. Cass needs to have a clear indication of who is poison because she has a small window to take advantage. This needs to function like how Yasuo gets an clear indicator that a target has been knocked up so he can react quickly. It also needs a timer of the poison duration.

Lastly, Cass ult is pitiful. She is an immobile mage after all and other immobile mages get way more reliable AOE stuns. It needs less of a delay and a clear indication of the range. The ult cone is hardly visible towards the end of its range.

Would all of this be op?
