Omg! I had just been thinking about this and had written up a proposal but hadn't published it. We could organically make common usage accept a single-syllable 7. Here's the writeup:

MAKE 7 MONOSYLLABIC

There is a lot of research that, in languages where the numbers have more syllables, native speakers have a harder time remembering sequences of numbers, because your brain has to store the cognitive load of saying it. So native Chinese speakers are much better at it than Spanish.

English is fortunate in in that all the digits are one syllable ... except for seven. If we could fix that, then we could cause a massive amount of good, when summed over all the times people have to remember numbers.

The good news is that we can promote this in a backward-compatible way, without having to coordinate in advance. Just commit to pronouncing 7 as "sen" (pretend you clipped the word as se--n), and eventually it will be the accepted pronunciation and codified as standard. As long as the listener is expecting a number there, they will automatically fill in the missing sounds and parse it as a 7.

Try it out some time! "Oh, there weren't very many, just six or sen."

Who's with me?

May as well just use sept from French.

That runs into the issue I was talking about in the proposal, where it's not backward-compatible and requires people to be informed of and sympathetic to the renaming. "Sen" will already be accepted as referring to 7, without such coordination, so long as it has enough context to be parsed as a number.

Sen’s good to me!
