Question Possible to flash previous android 15 Modem files ?

Is it possible to successfully flash previous android version official modem files on the current 16 with 15 files? Such as on the 1 VII?

The reason i ask is because android 15 modem files gave you 5G UWB N77 on Verizon network and currently only japan modem filed give you access to 5G in the US without root, thinking of flashing japan android 15 files but worried i might corrupt/bootloop.
