No room for architrave :(

We have bulkheads in our study an media room. Both rooms will have 2.4m high doors and the bulkheads sit flush with the door on top. Door frames still haven't been installed.

Once they go in we will probably gain 1.5cm or so to which we could fit the architrave. But would a 1.5cm architrave on all 3 sides look weird?

Should we do square set on top and a standard width architrave on the sides? Or just stick with a 1cm-1.5cm wide architraves on all doors throughout the house?
