The issue with transverse builds is the net coil tail length... the percentage of useable power loss will probably be double to triple that of a conventional horizontal or vertical coil.
In other words, a comparative loss of performance for the desired resistance... and in addition, the chance of a more "metallic" taste.
Try it... and build them as close as possible to a horizontal or vertical build baseline that you're familiar with. The worst that can happen is you're out a bit of supplies and time.
