I've done a bit of thinking about this. The first step I see is moving 
the variable setting from PHPTemplate to the core theme system. The key 
thing to realize here is that what is called from a module is not what a 
themeable function or template wants to receive. Node module likes 
calling theme('node') with a small number of arguments, but node.tpl.php 
  has a much larger set of variables.

The way I see this being implemented is adding a preprocessor step to 
theme(). If theme_foo_preprocess() exists, then that would be called 
with the original arguments and returns a larger set of, probably named, 
arguments. That function would be called in a themeable manner, so 
my_theme_foo_preprocess() could replace that argument preparation.

This would move a large chunk of code out of PHPTemplate into the core 
theme system where it belongs.
