No this is still a lot of work for very little gain.

The problem is that everytime a change is made in the first patch, all
the other three will have to be fixed and rengenerated.

Very few people really need cramfs if they're building custom kernels.
This is because initrd only makes sense when you're building for a
large number of machines.  If you're building a custom kernel, just
compile in all the drivers you need for mounting root and that's that.

On the other hand, the security fixes are usually easy to extract and
well documented.

Keeping up with the Debian tree is much the same as keeping up with
any other kernel tree.  The answer is to use a proper revision control
Debian GNU/Linux 3.0 is out! ( http://www.debian.org/ )
