You snipped the (for me) interesting part: did you notice how
`eval' jumps over the local declaration? It doesn't even /see/
it, the defun whithin the eval munged with the outer scope
(which might be buffer-local or just global).

You could as well have messed with the obarray [1] directly.

If this is what you want, fine. If it's not, think again. I can't
even venture a guess towards what you have in mind, I'm that bad
at interpreting what you write.

And then there is the issue of how readable your code becomes,
which will be important or not, depending on whether you want
others to read it or not.

Cheers

[1] Finding which obarray to munge is left as an exercise for
   the reader.
