Slider in slider?

Hi everybody,

I got the idea to make a section where I want to put a slider in.
And then I thought that it could be awesome that the background of this section could be like changing in the same time of the slider (with the same picture), but like with a little blur and a color overlay on it.
Does everyone know how to do this? Or have been ever confronted to this problem?

Thanks a lot for your help, have a nice monday!
