Having not done the sums and taken folks word for it 12mm won't make much difference to BB height on a bike where that height varies by about 5 inches anyway!!
Any issues running 26" wheels on 650b bike ?
Would 12mm make a noticeable difference?
Yeah probably. On some bikes (like the Coves I've owned) it'd be disasterous, but on others it'd just make them ride like Coves - great for pedalling over bumps but not so good at cornering and climbing.
I previously showed an example difference between a 26" Specialized Butcher Control (quite a big tyre, comes up almost the same size as a 2.5" Minion DHF) and a 650B Maxxis 2.2 High Roller 2.
The 26" wheel actually measured 27" in diameter. The 650B was 28.25". When compared with the same tyre but in 2.4" format, the diameter was 28.59" (similar width).
40mm diameter is a noticable difference. Also a ~20mm difference in BB height makes a massive difference. It can completely change how a bike feels.
Remember its not just the bb height that matters. Its the bb height in relation to the axle heights that changes ease of manualling etc. Dont forget that the axle to bb drop will not change. So bb changes not going to make ad much diff as it would changing it through shock placement etc.

boomting. you win.
The height difference will also affect the trail.
Whether that is a good thing or not depends on how you like your bike to handle.
I am trying to future proof my next ride, which will be a liteville 301, by buying 650b forks and using on my zesty with 26" wheels until next summer.
Did you run 26" wheels on 650b forks on your liteville and how did you find it?
