SOPP467: How to play the opening of Franck's First Chorale?

This question was sent by Jeremy, who is on the team of transcribing our videos into scores with fingering and pedaling. And he writes: It seems I forgot the Rep I was going to work on at the church yesterday. So, read through some of Guilmant's Practical Organist and started work on Franck's First Chorale. ​ Question: At the opening where it is written in the manuals, do you take some of the large stretches by putting the bass note in the pedals? Or do you play all of the bass notes in the pedals coupled only to the Great? Or just simply wince at the pain of the stretched 11th interval....? I was able to redistribute some of it between the left and right hand, but there is at least one stretch on the first two pages that seems to be physically impossible (I believe it is a E, B, G-sharp in the left hand with a wide stretch in the right. I don't have the music here in front of me.)
