used a regular expression to shim in a special comment. This
seems hackish but could a similar approach work on mssql? Is it possible to
hook into only the top-level/last Select's compile()?
Thanks for all of your help.

a CTE to the select and then generating
custom SQL for the subclass but I wasn't completely familiar of the
compilation workings to determine if this was workable solution to force the
CTE to the top of the generated SQL.

I found the following CTE demo (http://www.sqlalchemy.org/trac/
attachment/ticket/1859/cte_demo.py) and I was wondering if there was
any way to map these selects.
I have built a CTE based select to generate a dates table on the fly
and I would love to be able to map this and use generative selects
