Extending Vim really is a pain if you're trying to stay within Vim. Your best bet is to rely on piping output to other shell utilities to get the desired behavior. :r!cmd reads output of given command into current file. After selecting a set of lines with "V" you can pipe them through a shell command like so:
Vim commands string together pretty easily, and I've done some serious refactoring on good ol' C and ASM with this method back in the day.
These days I'm writing Java in Eclipse, which just doesn't have the same feeling to it.
:'<,'>!cmd

Yi sounds like a good alternative to Vi and Emacs: the philosophy of Vi, with the extensibility of Emacs.
The catch? It's written in, and it's extension language is, Haskell (which is why I've never used it.)

But then I found a really nice piece of software - Yi. It's a vim/emacs type (yes - both!) type editor. It's written and extendable in haskell. The keymap is implemented as a parser on user input, so keymap modules include vim (with modes / simple ex mode), emacs and others. The code is very easy to understand (I actually learnt haskell while patching it for my needs) and includes most standard features - tabs, buffers, editing, some syntax files... even basic ghci shell :)
It's not "ready" yet, but I would say it can be described as a "usable beta". If someone really likes the vim idea of editing with modes and is disappointed by vim's plugin model, then Yi is definitely worth a try.
