Have you thought about writing to the Lego corp and suggesting inch-high dolls? You could give them things like interchangeable heads and hair, or even legs. Maybe even tiny little hands that can grip on to things? I guess you could even do them themed ... pirates, knights, soldiers. Amazed Lego have never considered doing miniature dress up dolls for boys before. You could call them ... Hrm ... Lego Men?
But I guess that's not all! Think about all the fun people could have with dress up soldiers! "Men of Action", or, gee, "Joe who's a GI". You could give him a whole range of accessories and outfits and and and...
By dressup dolls I thought I clearly conveyed the idea of dolls whose design and accessories are all about dressing them up with clothing, makeup and fashion accessories. Not guns. Not tools. Not Batman-like gadgets/vehicles. Dressup dolls. Think Barbie dolls. The point being that dressup dolls and babies appeals to a large percentage of (but not necessarily all) actual real-life girls whereas action figures and guns appeal to a large percentage of (but not necessarily all) actual real-life boys. But you don't see people complaining about the lack of the latter for girls.

This is because however politically incorrect it is to point out, that girls and boys are different in basic fundamental temperaments.
Boys play competitive games where they either compete against each other or work together to overcome an objective. That's how my brother and I played back in the day. And growing up in the UK, we played with Action Men rather than GI Joe's.
Now, I have two daughters and they play cooperative games. The best description of girls playing that I've heard is "lets". I've heard my daughters playing together and they say "let's ..." all the time. They role-play scenarios with their Barbie dolls. And before they had Barbies, they did it with their stuffed animals. I'm a pastor and they often re-enact church and family stuff. They get details exactly right, including the pastor (me) working on his sermon on his laptop.
I have not forced this behavior on my daughters. And they like a few activities not normally associated with girls. My oldest likes shooting, has her own .22 rifle and is a pretty good shot. They both like wearing camo much to my wife's distress. They do play with lego and mega-blocks. My oldest has an Ubuntu laptop and loves it. But most of the time, they play traditional girls stuff.
