Yes, that's a valid feature request in my eyes (actually, I'll need them too 
for my own editions).

The slashed 6 in your example is apparently a very old variation. In most 
"modern" editions the slash is diagonally through the upper arc of the 6.

Basically, a complete set of slashed digits that I encountered so far are:

2+ with the vertical slash through the extended horizontal line of the 2
4+ with the vertical slash through the extended horizontal line of the 4
5+ with the vertical slash through the extended horizontal line of the 5
6+ with the slash diagonally (left top to right bottom through the upper curve 
of the 6

Note, however, that these slashed 6 digits were used mainly only in hand-
written scores and in modern printed scores. 

Many printed scores of the 19th centuries have the slashes for the 6 like 
lilypond. See e.g. page 8 of Mozart's Benedictus sit Deus, Alte Mozart Ausgabe 
(Wolfgang Amadeus Mozarts Werke, Serie III: Kleinere geistliche Gesangwerke. 
Leipzig: Breitkopf & Härtel, 1880. Plate W.A.M. 117.):

Mozart_Werke_Breitkopf_Serie_03_KV117.pdf

(The 4+ is printed as described above, see e.g. p.13)


On the other hand, some printed scores of the 19th century have the slashes as 
you suggest them
E.g. line 2 measure 4, or line 6 measure 1 of:

I have encountered the 5+ only once:

No, but it would be great to have it. 

Cheers,
