Substitute out the uppercase for the relevant base characters, and
you have it.

Actually, not, since with the exception of the b-stroke, which is
already encoded, they would be introducing precomposed characters for
sequences that are already representable with the characters already
encoded. The normalization forms (shown above: NFD, for the canonical
decomposition, and NFC, for the canonical composition) would have to
stay unchanged, so you essentially buy nothing by asking for
new Latin precomposed character encodings.

You might work with font vendors, to ensure that the glyphs that they
design work well for the combining character sequences listed above.
