There is some evidence for this, for example this article in today's Financial Times:
Muslim Brotherhood leader offers support to Syrian defector
The leader of Syria's opposition Muslim Brotherhood has indicated that his group might back a change of regime involving Abdel-Halim Khaddam, the recently defected former vice-president now presenting himself as an alternative.
http://news.ft.com/cms/s/11fb115a-7f22-11da-a6a2-0000779e2340.htmlIn return, Khaddam told Newsweek that "the Muslim Brothers now have enhanced their way of thinking, and they have come up with a new liberal agenda" (sic).
David Ignatius reported in September that the Bush administration was looking for ways to include the Muslim Brotherhood in its plans for regime change in Syria:
The Bush administration is debating whether to try to accelerate this unraveling with an explicit policy of regime change. President Bush is said to have expressed frustration with the conventional wisdom -- that the only alternative to Assad and his Alawite clan is rule by Sunni fundamentalists from the Muslim Brotherhood -- and asked his aides to explore alternatives. Soon after, a top Middle East expert on the National Security Council staff met for the first time with Farid Ghadry, head of a Syrian opposition group in exile. Ghadry told me he plans to convene by year's end a parliament in exile that would include all strands of the Syrian opposition,
including those in the Muslim Brotherhood who are ready to embrace democracy.

Oh, did I say "theocracy"? What I meant was "democracy", of course. ;-)
