I'd say the important bits are only slightly harder than doing the same with fq_codel.  Some of the less important details might be significantly harder, and could reasonably be left out.  The Diffserv bit should be nearly trivial to put in.

I believe much of Cake's perceived CPU overhead is actually down to inefficiencies in the Linux network stack.  Using a CPU and some modest auxiliary hardware dedicated to moving packets, not tied up in handling general-purpose duties, then achieving greater efficiency with reasonable hardware costs could be quite easy, without losing the flexibility to change algorithms later.
