Okay, I'll try to read it slower. 😳
Okay, supposed I need to do something similar, but much less exotic. Like, merely displaying exotic SVGA resolution (mostly 640x400) on modern LED screen properly, would I need that many devices?
Lol...sorry for all the info...and, ok I will forget you asked 🤣. I will try to be more succinct next time.
To at least try to answer your question though...I would have to say "not really" to "needing that many devices". You may be able to do it with just one device like the Extron RGB-HDMI 300A unit that works for some resolutions for me, for anything 640x480 and above (I am not sure about 640x400, but I think it might work). It converts 640x480 to 1920x1200 resolutions or 480p, 576p, 720p, 1080i, or 1080p to:
640x4806,8,9, 800x6006,8,9, 852x4806,8,9, 1024x7686,8,9, 1024x8526,8,9, 1024x10246,8,9, 1280x7686,8,9, 1280x8006,8,9, 1280x10246,8,9, 1360x7656,8,9, 1360x7686,8,9, 1365x7686,8,9, 1365x10246,8,9, 1366x7686,8,9, 1440x9006,8,9, 1400x10506,8, 1600x9006,8, 1600x12006,8, 1680x10506,8, 1920x12006,8,
2048x10801,2,3,4,5,6,7,8, 480p7,8, 576p6, 720p3,4,5,6,7,8, 1080p1,2,3,4,5,6,7,8, 1080i6,7,8
1 = at 23.98 Hz, 2 = at 24 Hz, 3 = at 25 Hz, 4 = at 29.97 Hz, 5 = at 30 Hz, 6 = at 50 Hz, 7 = at 59.94 Hz, 8 = 60 Hz, 9 = 75 Hz;
Check out the specs on this page:

I have had to use this RGB-HDMI unit in conjunction with another extron upscaler (VSC 300) to get some other resolutions to work (it does 560x384 to 1600x1280 resolutions but outputs to component or RGB, not HDMI, so you will have to connect your VGA from computer to VSC300->RGB-HDMI 300A->LED TV to get an HDMI signal, for example, if your TV doesnt support component inputs) -> http://www.extron.com/product/product.aspx?id=vsc300
You really have to look at all the specs to get an idea if it will work for what you want to do, but I would check out the http://shmups.system11.org/ forum as well for information. It's difficult to answer your question with suggesting just one device. Unfortunately it's usually more complicated in most cases, but I think you will find what you need with just a bit of research and eBay searching. Good luck.
