This is an expensive conversion, and while there are big fans of IGH here on the forum, I still believe that based on weight and efficiency, derailleur systems are better for sport and touring use. OTOH, having everything is a closed can is great for commuter and utility use, and may also make sense in harsh environments.
Based on my preferences, I consider IGH most practical in 3-5, or maybe 7 speeds, but don't see a need for something like a 14 gear IGH. But that's just me, and everyone needs to decide for themselves.
Before converting, understand that IGH on a modern vertical dropout bike means you'll need a chain tensioning device, which is somewhat counter to the spirit of IGH (my opinion) so I wouldn't convert a vertical dropout derailleur bike. If I wanted to build an IGH bike, I'd start fresh, with a frame more suited, either by virtue of horizontal dropouts, or something like an eccentric BB, or the Paragon moveable dropouts.
