Across history, many men converted to Islam out of material and sexual self-interest... One example I can think of is the priests of Zoroaster in Persia. They suddenly felt the need to adore Allah when Persia was conquered by a Muslim army.
Personally, I feel it is dangerous to gamble with religious belief in such a way. Allah, if He exists, may not look kindly upon someone who chose Him (against Christianity or another religion) mostly out of worldly interests.
Besides, Muslim countries tend to suck if you like a minimum of living comfort. And I would be too afraid to end up on /r/watchpeopledie after a slight social mistake.
