With runway configuration like that you won't be limited by TORA/TODA/ASDA. So just take the LDA and work backwards from that to see a range of aircraft that would work for you.
The Lear's tend to be play for sales on the fact that they are faster than some of the competition - but in the real world is it really so important to get to your destination potentially just a few minutes earlier on a typical European journey - especially as the most important parameter that usually determines flight time is whether Spanish/French/Italian controllers are working to rule or not? I would trade speed for cabin space, reliability, and resale value any day.
As Dudeness said, a Sovereign might be a better bet.
