If it's a rim brake wheel it's possible to have it rebuilt with radial spokes, heads-in, which will make it a couple of % stiffer sideways.
And if the brake rubbing problem was from a wheel that was flexing ON TOP OF the hub (the hub staying stationary, like in a solid fork) then stiffening up the rim/spoke system would help, a small bit. But I think the OP will find that the fork's flex is FAR greater then the wheel's. Andy.
