I wld recommend the airport transfer bus if possible for a number of reasons
If u take a taxi you are leaving the airport at a fairly crowded time 8 pm saturday does see traffic specially due to the construction work along the route from 9w domestic terminal to the international terminal.
Additionally, it is a short distance and though the prepaid taxi counter will process your fare, in my experience there is no taxi alloted at the counter so when you come to the taxi stand most drivers when they see the short fare pretty much refuse (i know its illegal but its happened to me many times) or demand extra (that is if you manage to corner someone) -being a mumbai you want to avoid this hassle
I recall that the airport transfer bus on the other hand keeps you airside avoiding the mumbai traffic - though the distance is short, it is a congested route
If you are worried abt the time and if u have an earlier opton from maa it is defintely worth making the change - the change fee can be as little as rs 750 ($17) - that is how much i paid this dec for a IT change del-bom sector
