Thinking about it some more, you can get more easily away with the "eh" in MEH (not the /ə/ but the /ɛ/). That way you'll sound like someone speaking with a The Hague accent, and if you're otherwise speaking English, this will most probably slip by completely unnoticed to most Dutch listeners (unlike OU or OI would).
Using the MOUTH vowel in that word would reveal an English speaker immediately ;-) (Germans mess it up differently ;-) )
