I think no, the main reason being that if Jesus was married, why would they want to hide this?
Additionally, if Jesus' real message differed so greatly from the message we know today, why would the powers that be even use Jesus as a reference point. He's not very well documented, despite what someone else in this thread bizarrely asserted. If Jesus were married, why would an anti-sex movement make him their symbol? Why would they see a passing, second-hand, after-the-fact references to a married guy and say "hey, let's retroactively make him the founder of our weird anti-sex cult" rather than just invent a fake person, who would be only slightly less documented?
First of all the Christian Church is and was never anti-sex. The adoption of ecclessial celibacy among one branch was purely a matter a political and economic matter and this have the Catholic Church never hidden. They adopted it, out of a fear that the clergy should become class people was born into, and to ensure the Church continued central control over Church vast properties. Even today a major argument against ending celibacy is that it would mean that priest suddenly should have a wage a family could survive on.
