That looks suitable.

Whats the deal with BMX BB + cranks, my tiny mind says if it's a Euro BB then the bearings/cups and crank axle will fit into a 68mm MTB BB shell, even allowing spacing of the chainring? So it just a matter of staying away from Mid and Standard BBs, Or is there some other magic going on?
I have a 107mm square taper in at the minute, and chainline issues mean it's going to have to stay that length, any ideas on spacing a coaster hub sprocket out?

There's loads of info in other threads about this, but yeh your basically right. BMX cranks are completely adjustable (profile 19mm / primo 22mm). You can change the shell width (cut the tube spacer) and chainline to suit anything.
