Should be pretty damn easy to swap over - OEM would be the easiest to do, but may be hard to obtain? Aftermarket bars tend to not have the positioning locators drilled for the controls - most people just file off the locator pin as its plastic anyway and isn't strictly necessary.

Risers is completely dependant on how you like your riding position. If you are comfortable now, then there is no need (if you get bars with the same profile). Risers will obviously give you a more upright position when fitted
