There are many two-syllable words stressed on the first syllable for a noun usage, or on the second syllable for the verb sense...
address noun – the location of a building
address verb – to write down an address OR to speak to a group of people
compound noun – something made of two or more parts
compound verb – to combine or add
contest noun – a game or event of competition
contest verb – to challenge or dispute
contract noun – a written agreement
contract verb – to make smaller in size
I got that list from this Wordpress blog. I can think of one case where the shift is from noun (arithmetic) to adjective (arithmetic), and there's also unionized (labour relations; organised into a union) and unionized (chemistry; not ionised). Offhand though, I can't think of any word where the meaning changes according to the number of stressed syllables.
As @Peter points out below, there are cases such as Rainier (the mountain) with two syllables, where rainier (more rainy) has three syllables. But those are really two different words with different origins, rather that the same word with different meanings according to enunciation.
But I get the impression OP is actually asking if he can "creatively" vary stress patterns in order to effect a change in meaning. To a first approximation I'd have to say No, you can't do that!
Dictionary pronunciation guides excepted, we don't normally indicate the stress orthographically, so you'd need to be in a spoken medium anyway - and unless your audience were primed to expect "meaningfully non-standard delivery" (a poetry reading from a respected writer, perhaps), they'd probably just assume you weren't a very competent speaker.
