I don't have any means of testing the impedance. That's why I was thinking of removing antenna central conductor and soldering an rp sma connector central conductorWelcome to AAC.
Connectors are convenient but parasitic. They should have a characteristic impedance that matches the transmission line, but they will always cause insertion loss, however small. If you properly solder the coax directly, you will have the correct impedance and less loss.
If you don’t need a connector, you will be better off directly connected—all other things being equal. Since there are many factors involved, empirical testing is certainly appropriate, but there in nothing inherently wrong with the idea.
Testing would be by checking the transmit strength and the receive sensitivity compared to the connectorized version. You would most easily to this using the RSSI function. If you place two modules at a relatively long but fixed distance apart and make the changes to one of them, you will see if performance is degraded or improved—or the same.I don't have any means of testing the impedance.
