My main concern is that at the band of design
frequency the transmitter is only designed to handle 1.5 SWR max. I'm
afraid that I might break it since our matching network already changes
the SWR to a peak 1.40 to 1 at certain frequencies on the band.

I may have other idea. If I add the return loss of the devices, would
that allow me to somehow find the SWR?

Measure the impedance of the system (using low power). That's the only
way to know for sure.
