More soldiers available in future backer builds?

Are future backer builds going to add more possible soldiers? just enough so we can play with our own squad setups? I’m getting a bit bored of the current squad I’d like to mix it up a bit.

I’m already assuming the technician will be added to the build at some point.

It could be something as simple as a choice from 2 Assault, 2 Heavy, 2 Sniper and 2 Technicians.

At one point the backer build will include the strategic layer to some extent, and that without squad-making sounds strange, so I would bet on yes.
