I have run hundreds of feet of MP film through still cameras without any problem. I actually prefer it as it lies flatter in the negative carrier. The only problem that I have encountered with color negative MP film is that it is designed to be printed on color positive stock whic does not have quite the same 3 response curves that color paper has. Usually this means a slight color cast in the shadows to avoid any cast in the hightlights.
Processing these color films films is easy if you mix your own chemicals. Consider them like C-41 films with an extra step to remove the REM jet backing.
With BW films you can increase contrast by developing longer. It's not so easy with color negative film since there are 3 separate layers. Increasing development time would have the greatest effect on the top color layer. But adjustments can be made to the developer.
MP film stock is not that much thicker than still film stock. However it is stiffer. The main difference is that only 30 exposures will fit in a cassette.
