Two possibilities: since you're using cape, use `cape-super-capf' to
merge a bunch of cape capf functions into one.

Other possibility: use `completion-table-merge' in exactly the same way.
This should be the general version of what `cape-super-capf' does.

Please try both and report back! I'm very curious, as well.
