Has there been any consideration of practical alternatives, such as
selecting a lookalike or similar character from the plethora of those
already encoded and promoting its use to represent the "newpi"
character?

Some possibilities which come to mind are:

The Greek letter(s) SAMPI, which is a PI turned sideways, comes in
two flavours, capital and small. U+03E0 and U+03E1, or in UTF-8,
Ϡ and ϡ.

The Cyrillic letter SHA, capital and small at U+0428 (Ш) and U+0448 (ш).
(Well, it probably looks too much like Roman Numeral Three at U+2162 (Ⅲ).)
But, another Cyrillic letter looks like an upside-down PI with a tail, U+040F
(Џ) which is Cyrillic DZHE.

Remote possibilities might include Reversed pilcrow (⁋) U+204B, Peso sign
at U+20B1 (₱), Double-struck capital PI at U+203F (ℿ), Element of Opening
Downwards at U+2AD9 (⫙), Yi Syllable CUOP at U+A2BC (ꊼ).

Or, since the "newpi" glyph could be considered as a ligature of PI and PI,
perhaps the character should be formed by U+03C0 plus U+200D plus U+03C0?

Best regards,
