I'm no guru, but I'm very sure it won't work.

You could do this on a second machine, or in a chroot, or in a virtual 
machine, and then distribute the binary packages. Which would be quite 
some additional work.

I'm running KDe 4.5, and it works fine. That is, there are fewer new bugs 
for me than were fixed.
