How to include two bootup logos in the kernel and choose which one to load via kernel bootup arguments

Hello, I have two identical embedded devices where the only difference is one has a 5" screen and the other has a 7" screen. Currently I created a custom boot up screen for our 7" version and stored it in drivers/video/logo/logo_custom_clut224.ppm. On bootup, it shows up fine. Now I would like to figure out how to create another bootup screen for the 5" version and store it in the kernel as well ( perhaps drivers/video/logo/logo_custom_clut224-5in.ppm ) In u-boot, I can detect which version I have by poking our devicetree blob however I'm not sure how I would dynamically tell the kernel which image to use. Any ideas regarding how to do this would be greatly appreciated. Thank you, Davis
