Starwars should fit into a TV series REALLY well if its directed properly.
The biggest weakness they could fall for is going for the formula approach of repeat structure each week with some variation at the start and end of the season. Whilst that is doable it would be a lighter affair and wouldn't likely work as well as it does for something like Star Trek. Instead I'd rather see it Game of Thrones style - ergo tight storyline with each episode building into the next.
Starwars also has the major bonus that its got a huge amount of content for such a series; I think they'd likely keep it all within one time period and character group; but they could certainly use it to add flesh to the bones of the films and expand on background stories and elements. What time period they choose would be interesting; the most jarring would be to pick the 4 to 6 episode period as with the technology on show in 1,2,3 and 7 the middle three films kind of stand out as a sore thumb today. I could easily see them using it to bridge into the newer 7-8-9 block of films - heck maybe even try to give some depth to the convenience of the 7th film storyline
