Surrogate character to visualize a space like ̺ this, but without combining?

I'm looking for a character in Unicode like this (in black):

The problem with COMxadBIxadNING INVERTED BRIDxadGE BELOW (code point U+033A, xCCxBA in UTF-8) is that it must be combined with another character. I need the character stand-alone.

Combined with a space: ̺ (easily lost if you try to delete the character to its left-hand side)

First letter of word, non-spacing bridge, rest: ̺Not ̺what ̺I ̺want (N̺ot ...)

Is there such a character, a non-combining, spacing inverted bridge below?
