Not at all. There are many men and women who date and consequently marry the siblings of their brother-in-laws and sister-in-laws. Some folks may find it strange to "keep it in the family", but there are many success stories of this nature. Technically, your brother or sister's in-laws are not YOUR in-laws, and you have no real legal relationship to them. If my fiancee had a nice brother for me to set my younger sister up with, I'd go for it in a heart-beat.
