I think it will look disproportionate and clumsy with 90 mm wide stringers. I believe the other suggestions you received with finger joints or your own joint over the footing are better.
If you want to build your own beam, build it in height instead, like with 3 pcs 45x70-95 in height instead (as a glue-laminated beam is constructed)

Thanks for your input!
I have modeled the stairs in 3D and I think it looks OK in terms of proportions. Somewhat chunky stringers, but I've decided to go with 2 pieces of 45x220 (meaning I will assemble four pieces to get the right length). Lumber purchased, so soon I'll start building the stringers!
Snyggt is having similar thoughts: building a staircase in our slope, how much needs to be done underneath? Can it be placed directly against the grass?
Hmm, googling a bit and can't find a huge selection of pressure-treated glued laminated timber. Does it mean you have to special order?
Why do you need it pressure-treated? I've built a few free-floating outdoor stairs with untreated lumber and the stringers lasted 10 years and were in good condition. It's usually the tread attachments that tend to rot if they're constructed incorrectly.
Why should you have pressure-treated wood? I have built some free-floating outdoor stairs using untreated wood, and the stringers lasted for 10 years and were in good condition after that. It's the attachments of the treads that usually rot if they are poorly constructed.
I would like to know how to build it if you're going to lay it on a grass slope.
