I wonder if there could be an easy way to just sort of restrict how much air actually passes through the MAF sensor, rather than having to put it in a larger tube?

I dont think you would have that issue myself. At lower airflow the car is running in closed loop anyways so the MAF is not really watched at all anyways. All you would have to do if you were having issues at lower load is just pull the car out of closed loop later and let O2s deal with the resolution down low.
It was discussed a bit earlier in here that you can just move the maf closer to the wall of the tube and because you assume laminar flow through the pipe the velocity of the air moving near the wall will be less.
I think if you go to big you will cause turbulence in the piping since they are relatively short to begin with and you need that smooth flow to be able to accurately meter it.
