SM-G900T3 Downgrade to KitKat?

I just got a Galaxy S5, and it came with Lollipop installed (5.1.1). I'd like to downgrade it to KitKat (4.4.2) but no KitKat Firmware for this exact model is available. However, there is 4.4.2 Firmware available for the SM-G900T and the SM-G900T1. Would the Firmware for one of these models work? Thanks.
