You can mount your new bigger ring on the inside using a longer BB spindle or on the outside with a shorter BB spindle....either way should give you a close enough chainline.
it's not the crank clearance or the spindle length that's the issue. the issue is the chainline. if i move my chainring outboard of the spider, the chainline will be wiggidy-whack
