yes, with varying degrees of sucess
i would try Resolve's opticalflow first, it's fast, and it's pretty good
interpret the clips at 15fps in the media pool,
set project speed setting to opticalflow / large / better
drop clips on a timeline,
set "change speed" to 24fp
if your machine can run it, it's now running real time, otherwise you might need to cache

if that's not good enough, there is many other options - VFX, image restoration and finishing software all offer roto tools to sort boundry regions and create layers for the optical flow to caculate seperatly, as this is the far most likely thing to give one problems, not the speed change on any one object, it's the area where one moveing object passed a slower or non-moveing object and the software creates artifacts.

Assuming your system will cope, follow Dermot's instruction.

start a 25fps project,
change speed to 25
the rest stays the same

good luck!

any other option will take far far far longer, so hopefully this will be workable
