All is possible but not all should be done, especially not features that 
mostly serve a few viewers (like acrobat) and don't really relate to 
typesetting.

That said, we can add some styling. First of all, you can use a bit of 
abstraction

\defineinteraction[one]  [color=darkgreen,style=\underbar]
\defineinteraction[two]  [color=darkred,  style=\underbar]
\defineinteraction[three][color=darkblue, style=\underbar]

\def\inone#1{%
   \start\setinteraction[one]%
   \goto{#1}[url(#1)]\stop}
\def\intwo#1{%
   \start\setinteraction[two]%
   \goto{#1}[url(#1)]\stop}
\def\inthree#1{%
   \start\setinteraction[three]%
   \goto{#1}[url(#1)]\stop}

which already might help you. To make it easier I'll add \namedgoto do 
that one can say:

\def\inone  #1{\namedgoto[#1]{#1}[url(#1)]}
\def\intwo  #1{\namedgoto[#1]{#1}[url(#1)]}
\def\inthree#1{\namedgoto[#1]{#1}[url(#1)]}

I'll also add \outline and \outlined

\defineinteraction[one]  [color=darkgreen,style=\outlined]%
\defineinteraction[two]  [color=darkred,  style=\outline]%
\defineinteraction[three][color=darkblue, style=\outlined]%

which of course you then will wikify ...

I attached an example but there is no upload (will happen when the build 
is running again because I can't make osx bins here).
