As commonly misunderstood "horn section" in the classical orchestral sense does not imply a section of french horns, trumpets, trombones (and tuba(s)) - but a FRENCH HORNS section [[[[[:)]]]]]
Oh and btw, 8 horns are quite unusual but 6 are very common.
The trademark Goldsmith Horn sound comes from micing the instruments fairly distant (a hotter A/B (conductors mic) pair signal) that allows the horn sound to travel around in the hall (resonate) and evolve into their full, thick and beautiful smooth sound before it is picked up by the mics.
James Newton Howard and James Horner are also fond of horns.
Horner utilized two sections of 4 horns on each side of the recording stage for his score to "The Perfect Storm", with great effect.
James Newton Howard challenged his musicians in "Wyatt Earp" and wrote high E, 5 or 6 times in one cue. First for solo horn and later for the horns in unison. They appear to have no trouble at all on the score [[[[[:)]]]]]
My vote is for this horn section of 6-8 french horns.
Intimate divisi (two desks perhaps?) strings would be nice too!
All of the available alternatives are of interest to me, except saxophones.
I truly hate those instruments in orchestral settings. If you were to sample
saxophones it would have to be recorded with solo jazz in mind, I think. This is where the instrument is at home. Calling for saxophones in an orchestral piece is like building a Zoo on the North Pole with exotic tropical animals from Africa....
I served one year in the army as a musician in an army band, and even though the musicians were great the sound of the saxophone group started to annoy me very quickly. The massive clarinet choir was also a tad too much for my liking [[[[[:)]]]]] (Clarinets and soprano saxes are pretty similar in sound in tutti parts)
Clarinets in unison is also a terrible sound. Closer to an accordion than anything else. Having said that, though, the dynamics of the clarinet (from whisper soft to loud and blaring) by far outweighs the sonic deficiencies [[[[[:)]]]]]
Oh, I'm rambling [[[[[:)]]]]]
6-8 Horns!!
