Well, yes, it would take time, but surely not more than compiling everything on it?
There's multiple ways you could do this:
- nfs-mount /usr/src and obj
- copy them over only if needed
- do a binary-upgrade, with sources you compiled
They're all quite workable. I've done the first with nfs over IPSec, about 50ms. latency. Not fast, I'll give you that, but practical and fast enough (for my use at the time at least).

Yes, but whatever space that frees up for you, you couldn't really use freely anyway, since you'd need that space again for the next build?
