It is both reasonable and unfortunate that TrueType & OpenType fonts can have no more than 65,535 glyphs. That said, probably the logical font made of multiple physical fonts can be probably made to support all available planes.

Yes, that's how you can fit all of Unicode into one "font" -- use a collection of fonts with at most 64K glyphs each:

I'll leave it as an "exercise for the reader" to generate such a font.

Wow, I did not know about that limitation. That's pretty interesting.
