Given that you can’t reliably predict the actual wifi throughput from userspace, and that it will vary over time due to external interference and path attenuation, that would be difficult.
However, you *can* loop both the ingress and egress traffic through a common IFB interface, and shape that - using Cake, even. That sounds like what you’re trying to experiment with.
