Sounds like a plan.

And do put the chainring on the inside of the spider if you can stand the way it looks that way. (Some don't like it.) The more inboard you can get that ring up front, even putting spacers between the spider and the inboard ring, the less dish the wheel has to have. And the less dish, the stronger the wheel. And easier on the axle. Depending on how the chainring and chainstays play together, you might even get it to have no dish at all. And some singlespeed freewheels are assymetrical so you might even buy another mm or two there to avoid dish.
