This is exactly what METAL is for.  Most discussion of it centers on the 
more difficult slot-oriented page macros, but breaking out bits is quite 
easy. Instead of the tal:replace, you would write:

<div metal:use-macro="here/subtempl/macros/main"></div>

...and wrap the sub-template in a <div metal:define-macro="main">.  Now 
the subtemplate will be treated as part of the main template during 
rendering, and all variables will be shared.
