I Imagine these maps might work:
https://www.warlight.net/Map/1173-Imperium-Romanumhttps://www.warlight.net/Map/5745-Battle-Islands-V (for some reason hyperlink doesn't work)
https://www.warlight.net/Map/4179-Macro-Land (possibily the best one made for small 1v1 games imo)
Though it's important to note that you might need to adjust some bonuses etc. Also if the players start next to each other (assuming manual dist. custom will never work, and radom isn't skill) it'll be many unfun turns of building a huge stack before the game can progress. (a situation similar to this game :
https://www.warlight.net/MultiPlayer?GameID=2400706 After building for many turns (talking easily more than 100) I'd eventually be able conquer the rest of the map while keeping my opponent blocked), not very fun so to speak.
I'd heavily suggest that you make it 2 starting spots, as even if you were able to create a good template I'd doubt it would be fun (especially in the long run).
"If the question was posed "Who is the best WarLight player?" And assume I have the two best players before me. How would we decide in one game?"
Well as WL have infinite number of templates, deciding it on one game wouldn't make much sense (not to mention that players are strong on different settings:p) Anyway that's not the point, I'd think a small map (like macro Land), no-luck settings and cards (reinforcment, sanctions (both positive and negative would work, blockade/abandon/gift etc ) don't have to be many, but need to be a significant reward for capturing territories)
