I can't see much of a market for any of these bikes (the new ones, that is).
Anyone who knows what a board tracker looks like will find these sadly lacking in design cohesion and eye appeal.
The performance level is so low as to exclude most every motorcyclist.
The price will be too high for newbies looking at Chinese scootertoys to be tempted.
Not that an acceptable board track style bike can't be built (such as "The Flying Merkin"), but they will be custom (bespoke, as P B G correctly puts it), and THEY would be welcome in "Old's Cool", yes?
