I think you are overestimating how bad it will be, there are similar programs here and it seems as though the people involved get really tight, like a real little family. Is it only engineering students? are you sure there are no other programs running alongside? and it's not like there will be no girls. just become mates with the few girls there are, I can guarantee you they have at least one female friend who has one female friend and so on.
If it becomes really tough for you, transfer to another university next year.
just a little advice: Your negativity is gonna cock block you a bunch more than being in an alternate stream ever would.
