Default [Q] timeshift burst with higher resolution

Hi guys,
I think i have very intresting question to all devs. Timeshift burst make 61 photos in 2 seconds in resolution 1920x1080. It's exactly the same as recording in resolution 1080p.
Since we are able to record in 4k do you think that there would be option, to change resolution to 3840x2160? 4k recording is also 30fps which means that it record 60 "photos" on 2 seconds.
Or maybe we can do 120 photos in 1080p resolution since we are able to record 1080p in 60fps?

I hope that you get it what i mean
