Your preferred spellings, punctuation and spacing are beginning to look more like the 20th century spellings and punctuation used in the card titles of Marteau's 1930 Tarot de Marseille - which are all in modern French. Using Marteau spellings isn't necessarily a bad thing. Conver isn't the be all, end all of card titles names. (After all, Hadar thought fit to go even more retro with the card titles than those appearing in the Conver.)
The Conver spellings would probably make the greatest sense if you were making an antique-looking, woodcut deck. I don't know exactly what style your deck is going to be. But maybe you can go with modern spellings and punctuation and spacing. Many non-francophones know at least a little French; therefore, if you use 100% Conver titles and Conver's inconsistent presence/absence of apostrophe in L'xxxx, they may think that you've "mispelled" the titles. In fact, the fact of LEMPEREUR being spelled in the Conver as LEMPEREUP might indicate transcription errors, mistakes by unscholared printers, or as some pundits speculate, esoteric coding.
For consistency with the appearance of most of the titles in your list which are in modern spelling (including modern U instead of antique mix of U and V), punctuation and spacing, you may as well conform the few remaining non-conforming ones with modern spelling à la Marteau. Modern-day post-Marteau tarot decks in France generally use Marteau spellings and often replace any antique V's used by Marteau with modern U.
To conform with Marteau:
Le Bateleur
La Papesse
L'Impératrice
L'Empereur
Le Pape
L'Amovrevx (He uses the antique V instead of modern U, but you could use modern U)
Le Chariot
L'Hermite
La Roue de Fortune
La Force
Le Pendu
(Death - untitled)
Tempérance (note the absence of the article)
Le Diable
La Maison-Diev (antique V)
L'Étoile
La Lune
Le Soleil
Le Jugement
Le Monde
Le Mat
Marteau uses all upper case, by the way.
Note: I've left out the raised (mid-line) dots that Marteau placed between words in many of his card titles. There are dots between the words in all multi-word titles (i.e., all titles except those with one word or the article L'xxx), with the sole exceptions being Le Chariot and La Force.
I have the Conver decks, but the evening is running late, so I'll let jmd and Diana fill you in with Conver, if that's the way you wish to go.
