Halation simulation sliders including color selection

Can we get halation simulation into Lightroom? Specifically Lightroom on iPad, but all versions should get it. 
 

Film photography is big right now. Lots of people love the look of film. But being Lightroom users means we miss out on some aspects of film because LR does not have the necessary tools. 
 

Halation is something we need to open other apps for and we need to know a bit about using layers and blend modes and stuff like that.

Therefor it would be nice to just have this in the app. Here is what I’m thinking:

A slider for strength/brightness.

A slider for spread/area.

A slider for sensitivity. Meaning a slider that adjusts what part of the photo gets halation. Will it be only the edges around very brightest parts? Or will it be more sensitive so that it applies halation to less bright parts too? (Hope that description made sense.)

And lastly a way to change the color of the halation.
