Try keeping non-climbing exotic roaches such as discoids or orange head roaches. They don't require any messy vaseline barrier, and will not establish themselves if some should escape.
Another trick is not to refer to them as ROACHES. Call them beetles!
Lessee... other items to try besides discoids and orange head roaches:
silkworms
superworms
mealworms
houseflies (try skipio's)
>>I've kept Madagascar hissers before, so I'm knowledgable in the keeping of glass climbers...I'm just wondering how my landlord would respond to "Yeah, no crickets, just some roaches." Landlords do everything in their power (the good ones at least) to keep roaches out.
