Hi, Fatter digits for big tubes would mean (much) higher current, which is proportional to digit surface. This mean higher power consumption and also earlier end of the tube because of shorts caused by higher amount of sputtered metal from cathodes deposited on insulator rings.. but it is worth of experiment, one day..
