FT-710 on 8m TX?

Luckily, I have one of the few legal permits in the UK to TX on 8m. For the last year, I have used my FT817ND on 8m FT8. So far, with just low power and a low wire dipole, I have been copied on 4 continents and in 21 countries (it may be more now). 

I am curious to know if the FT-710 can be simply modified to TX on 8m just with button presses. Although I have no plans to use my FT-710 on 8m, I am just wondering. I am sure there will be wideband mods by changing diodes internally, but I do not want to do this.
