4/8 sharp IS a full sharp (as you know, the reference interval is always a whole tone). Therefore labeling it ^4 may be a bit misleading, but it's ok if you can use the symbols alternatively. Other than that, I like it.
Microtonal notation is mostly used to _approximate_ tonal events that can't be described with 12 TET (12-tone equal temperament). While a 7/8-tone sharp theoretically exists, one would rather think of it as a 1/8-tone lowering of the tone a whole step above. So, instead of thinking C 7/8 sharp, think D 1/8 flat.
Hmmm.... There is a semantic difference between ^d and _e. For instance, the Cmin scale includes _e, and the EMaj scale includes ^d. Under an equal-temperment scale, there is no difference in sound (both would be 7500 MIDI cents, if I'm interpreting the MIDI cent scale properly), but musically, they are treated differently in notation and meaning.
If there is no reason to specify ^7C, on the grounds that it would be easier to think of _1D, why not go further, and only specify _D, _3D, _2D, _1D, C, ^1D, ^2D, ^3D, ^D/_E, _3E, etc?
Actually, I could suggest another notation: _#C, where # is a single digit, means flatting C by that many eighth-tones. For finer control, _##C, where ## is a pair of digits, means flattening C by that many cents, or 100ths of a semitone. ^#C and ^##C have analogous defintions, but sharpening instead.
The note halfway between E and F could be represented as ^2E, ^50E, _2F, or _50F. F itself could be ^E, ^4E, ^0F, ^00F, F _8G, or __G (or, if you really wanted, ^^^D).

Proposed symbols for eighth-tone notation:
1/8 sharp: =` ( ` is back quote is ascii 96)
[snip]
3/4 flat: \ or ` `_
Example A `= would be middle-a eighth-tone flat or 6875 MIDI cents.
If these are the symbols you need, what about:
1/8 sharp: ^1 2/8 sharp: ^2 3/8 sharp: ^3 4/8 sharp: ^4 5/8 sharp: ^5 6/8 sharp: ^6 full sharp: ^ 1/8 flat: _1 2/8 flat: _2 3/8 flat: _3 4/8 flat: _4 5/8 flat: _5 6/8 flat: _6 full flat: _
Wouldn't that be easier?
Your example would be _1A (Accidentals come before the base note).
Let me know what you think.
BTW: Is there no 7/8 sharp or flat? do double accidentals occur in microtonal notation?
