Intertherm M3RL series 90+ Downflow Furnace.

I want to add a whole house humidifier to this furnace. It looks to me as if a return air bypass version, such as the Aprilaire model 600A, is my only option, but frankly I know nothing about this. I need knowledgeable advice. My biggest concern is if it is possible for a humidifier to be installed. See pic of the top of my furnace.

Ideally, this would work with my Ecobee 3 thermostat as the humidistat.
