No this isn't one of those stereotypical kind of things.
But i was watching some crossmen lot videos (amazing bass line this year), and a girl played bass four.And it inspired me.Because this girl didn't look like she normally carried 30 odd pounds around.And i figured i would show it to my line.
Just in case they start saying "it's too heavy!".

Does anyone on your line play a unusual size for their build?

At Raiders the smallest (in body size, not height) played bass 5.

at a school near mine there were two girls on the bassline and they played 4 and 5

Hey now. Us top bass ladies are cool too =P

Anyways, I haven't seen many lines at all that put girls on the lower basses. I don't know if it's because of the players' chops or because of their height and build.

I carried the bottom bass my first year in high school. I was about five feet even and not much more than 100 pounds. (Thank God for the growth spurt I had the following year!)

It was pretty obvious our instructor set the line strictly by hands without considering body size. There was little ol' me on the bottom, but our #2 bass might've been the biggest guy on the football team's offensive line.

we've had girls play 3 (of 4) for like 3 years running

That's an amazing feat.

I applaud you.

I have the best hands out of our entire bassline, but since our instructor didn't set the bassline in any paticular way, I ended up on fourth. At first I didn't like it much, but now I'm digging being a 5'4 110 pound girl on a 24 inch drum. I've found that you get a lot more respect from guys when you march a larger drum.

yea its pretty cool, we have 2 girls on our bass line at my college, I wish I was on it though, I got stuck playing my primary insturment, the mellophone

hehe.....this was our tenor captain for 4 years.
