It seems unusual, in the midst of this tractate that discusses polygamy so extensively, that the Gemara discounts the idea that such a messenger might wish for a second wife. How should the 'rumors' or suspicions touch his credibility any less on account of his one wife, if he indeed offers to marry this ??????

You touch upon a very interesting point. This, and many other Gemaros, is the basis for the position of Rav Reuven Margaliyos zt"l (most famously author of Margaliyos HaYam on Sanhedrin)that while it was theoretically permitted to have two wives until the Cherem of Rabeinu Gershom, in practice this was already deemed generally unacceptable from the times of the Mishnah and on (and perhaps earlier).
All the best,
Yaakov Montrose
