GL-X1200 modem compatibility

I am looking at the GL-x1200 router and want to replace the modems with two sierra em7511 with m.2 sleds, beyond needing m.2 sleds, and mf4h pigtails or new bulkheads, will drop in and go work? i am looking at running them in mbim, but could do qmi also. I don’t see a r00ter build for this router. any help is appreciated. thanks

Never work with the modems.

The only one we worked with is mc7454 from Sierra.
