Pelican.com lists the interior dimensions of the 1550 as
18.43" x 14.00" x 7.62" (46.8 x 35.5 x 19.3 cm)
Here's a quick sketch to make sure that I am understanding what you're thinking. I've also noted the dimensions with letter designations so it will be easier to identify actual dimensions you want. Let me know if this is what you are thinking.
