As Keith reports, modified FT817NDs may TX on 40MHz (8m). If mine does, it means I may be able to TX WSPR or FT8 on 8m, albeit with external filters.
I may try asking OFCOM for a permit for the next Es season and see what happens. They can only say no.
Maybe I should ask for a band and 10W? Personally I would be happy with a spot frequency, limited time and 5W on an NoV. We shall see. It would pay me to apply in good time. Of course, if there was any "harmful interference" issues, I could be closed down.
I am sure just a few watts of FT8 or WSPR would be audible across Europe given decent Es.
Personally, I think several people should apply. The more stations active, in more countries, the better.
