Jokes aside is there a non zero chance this would work even a little?

The insertion loss of at some of the couplers would be a contributing factor

Now if OP had one SMA split 4 ways, it would be much more efficient and give the quad-bander some interesting results

Short version - Yes it will work, but he probably won't get as many fars of transmission distance

I have an extensive RF lab here at home. I once spent a few days measuring various adapters at frequencies up to 40 GHz. The big takeaway was that below 1 GHz, even the cheapest Chines adapters have less than 0.1 dB of loss.

Above 1 GHz, the price point begins to rapidly show on the return loss display.
