Irish AEC class DMU look alike

[jimr]

New in the USA to Irish rail modeling. I was able to get a hold of an AEC class look alike DMU pair in dark green livery. I'm curious how you long time modelers feel about partially respraying a look-alike set. My thought is to leave the lead DMU in it's green livery and respray the trailer unit in black and tan livery. I once saw somebody spray one side and one front end of the set in one livery and the other side and back end in a second livery. So depending on which way you're viewing it, you see two different liveries. I'm sure you prototypical fans hate this idea. But I like the idea of displaying two different time periods. Let me know your constructive thoughts. I appreciate the input.
