If I can confirm your settings, I could add it as an option in my new tool here:
https://github.com/biscuits99/rp-video-manager

If we just focus on SNES for the moment, then I can apply it to others by largely just updating the resolution settings.

Can you see if this content in your /opt/retropie/configs/snes/retroarch.cfg achieves what you expect?

video_shader = /opt/retropie/emulators/retroarch/shader/crt/dotmask.glsl
video_shader_enable = true
video_smooth = false
video_scale_integer = "true"
aspect_ratio_index = "22"
input_overlay = /opt/retropie/emulators/retroarch/overlays/effects/scanlines/scanlines1920x1080-5x.cfg

input_overlay_opacity = "1.000000"
custom_viewport_width = "1536"
custom_viewport_height = "1120"
custom_viewport_x = "0"
custom_viewport_y = "0"
#include "/opt/retropie/configs/all/retroarch.cfg"

It would also help if you posted your videomode file:
/opt/retropie/configs/all/videomodes.cfg
