Another concern is IF there is 3G-specific stuff in the kernel. If the 3G stuff is all loadable kernel modules, then probably no problem with kernel differences.

Its just ppp over a usb serial line. Other than standard kernel drivers for usb serial, nothing special about the kernel.
Hmm...
It seems that I have seen a "firmware loader" in some of the images I have looked at which would do a firmware upload to the "other arm" (3G card) on boot up.
But the one(s) I was looking at didn't have a firmware image to upload (just using the default image in the 3G SoC).
That would be another good reason to keep a copy of that "broken" firmware image. There might be a GB specific 3G SoC firmware image in it.
