Years ago, I purchased 95 full edition, followed by 98SE upgrade edition, followed by ME upgrade edition.
Logic is, you could upgrade or do a full install, so long as you had a prior version, eliminating need for all the other ones. IE 98 + 98 Upgrade & 98SE + 98SE Upgrade editions could all be replaced by 98SE Upgrade edition.

I took the 98 CD & created an ISO image of it, then deleted all the useless folders leaving just the 98 Dos Utils & the win98 setup folder. Next, I imported Win9x from ME disk & renamed it ME. Same for Windows 95.
So, I ended up with an all-in-one disk after I saved the changes, where I could either launch 98 setup, or just go to the prompt & choose CD ME, setup & install ME, etc.

Now, years later, I have a newer PC that refuses to boot from that. So I tried making a modified flash drive that is a bootable USB flash drive with pretty much the same.
It sort of works, or that is to say, it gets to installing it, but around the 10 min mark, it seems to always error out or something. I am working on fixing it, & I hope it gets better. Previously, I had the problem that it would try to use the flash drive during install, even if I DOS CMD copy the setup files to the hard drive first & then run it from there.
This could be tricky! I will have to update you all later if I ever do get it working. Meanwhile, if you guys have ideas...

Wonder if it could be set to use XP install disk via using the Repair Console to launch the installer? Hmmmm!!!! XP + ME + 98SE + 95? Great!
Wish me luck!
EDIT: My idea is, copy the 95/98/ME folders to the root of the XP disk, then from Repair CMD prompt, navigate to said folder & run setup. Problem is, I believe, it makes it too big for a CD, so I will have to try DVD unless I figure some way to get rid of a few files...
