Default Tmovil to rogers 4.4.2 is safe to flash?

Hi everyone, i got a question, i hope someone can help me whit this,

After read everything about flash and brick and not downgrade firmware i got the question...

Can i flash the complete rogers firmware over the tmovil firmware?

The two firmwares are in 4.4.2 and the bootloader versions are the same ..... In that case it will probably safe?

Thanks to all...
