You want some Lesotho or Transkei highlands … they will Finnish and handle the cold very wellI gave some RSC Lao, Malawi 2020 and Himalayan seeds to a friend, who grows in a badly isolated shed.
The temps there are far from perfect this time of year; during the day it never exceeds 18C (64F), in the night it's hardly 15 (59F) or even lower.
Still these RSC sativa seedlings are growing remarkebly well under these conditions. Especially the Lao, from which I least expected it considering the tropical climate, performs suprisingly well.
Next time I will throw in some pictures.

I tested these, U.K .i started them late summer
Just left out bottom of garden
You can see the dates on photos , very cold tolerant
that is what I told in post #6 of this thread.You want some Lesotho or Transkei highlands …
...But I don't understand what your problem would be: those winter temperatures are subtropical/Mediterranean... I wish I had that minimum all winter in my mountain range... With them you can grow almost whatever you want, and without a greenhouse.I want to know if it would be possible to grow longflowering tropical sativa's in colder climates with good results?
Daytime temps would be at most around 18-20 degrees C (64F - 68F). Nighttime around 15 degrees C (59F) at the roots (at the leaves colder).
Most cannabis plants are pretty though and versatile. Most indica's and hybrids handle this without to many problems.
So would real tropical sativa's be able to handle these temps without too much problems, or is this a lost cause because of the huge differences in habitat?

Word on the bro science. I grow in a cold and wet environment and indicas tend to have a lot of issues here. People only grow them because of a short outdoor flowering season.
Have you considered growing autos? With autoflowers you could keep your lights on 18-24 hours a day and help keep your temps up, especially if you're using a recirculating ventilation system.
