YES! We got the 5300 logic board working with the 5300ce screen! Having put the 5300 together again, but with the larger hard disk from the 5300ce, we connected it to an external monitor and played around with the monitor settings (including video mirroring vs multiple screens). The results were interesting but entirely logical, and not relevant here.
Then we removed the entire screen assembly from the 5300 and replaced it with the one from the 5300ce. Success! It worked just like a 5300ce except for the number of colors! When we set it to "thousands", the screen went white again, but clicking immediately on another setting got us out of it! Josh Watson (quoted below) seems to have been right about the number of colors! I'm guessing that the Monitor [& Sound] Preferences (or whatever) on the hard disk of the 5300ce into which we originally put the 5300 logic board had been set for thousands of colors. Presumably, when the Welcome screen is replaced by the Starting Up screen, the video settings are switched to those on the hard disk. The latter settings are automatically modified if they are not compatible with the particular computer's video hardware, which is why the thousands-of-colors setting on the hard disk "went away" when the drive was put back into a non-hybrid 5300. It should be noted that, when the 5300 logic board is connected to a 5300ce screen, the option of thousands of colors appears among the choices offered by the Monitors [& Sound] Control Panel, while this option doesn't appear when the original 5300 screen is attached. But, in the latter case, other color options do appear! My inference is that there's something in the screen electronics that lets the 5300X logic board distinguish between displays that come with 512K vs. 1024K VRAM, but not between those that are color vs. the one that's grayscale. (Thus it doesn't distinguish between the 5300 and the 5300cs!) For whatever reason, the logic doesn't determine the amount of VRAM present by actually checking it, and probably doesn't have the circuitry to do so. What worries me is, what happens if someone carelessly sets the number of colors to thousands and doesn't correct it while the Control Panel is still there! How does one get out of it? Is it enough to hold down the Shft key when starting up? Otherwise, does one have to have an external drive or floppy disk with a system folder that has compatible Monitors settings? I don't want to have to find out the hard way.
