No it's not like chasing hands.
At what point does getting hit become that likely? When you throw back the lead leg and scoop with the rear hand? His rer hand is going to be much too far away to land anyting worthwhile, and his lead hand is going to have no power from having it's corresponding leg in the air, trying to kick you.
I think you guys are picturing something all together different from what I am attempting to describe.
If not...well, I pull this in sparring all the time without getting countered. In fact, I will try for this in my fight this month and try to post a vid to prove this works, and works well.
I actually love scooping kicks; my concern was as Whiteshark was saying; it's easy to try to scoop a kick that's too low, which leads to breaking your guard and bending/crouching too much. This might seem more likely to me because I tend to target inside leg kicks just above the knee (at least with the front leg), and that's pretty low to scoop, especially since with that inside leg kick I'm not turned over as far as with an outside kick, so I'm more likely to be in range to exploit it if you lean or something. For a kick to the upper thigh or higher, my favorite counter is the switch and scoop, followed by kicking the back of their kicking leg with the leg I just switched back.
