In a future where a large company is launching a series of interstellar colony fleets to nearby star systems, would it be feasible if they modified the English writing system and Earth kept to the original English forms?
The basic idea is that the owner of this company has always had an issue with English and wanted to modify it to make more sense phonetically. To do this, he created a writing system that was more reminiscent to older English languages that incorporate letters such as Thorn, Esh, and so on. As well, he incorporated some Greek and Cyrillic letters as to create the necessary sounds. The end result is a language that is identical to English when spoken, but visually looks foreign.
One idea is that he required the passengers to learn and use this language in order to be admitted on to the colony ships. Using the power of story telling, I can easily create the reason for why the language will be used and enforced. But my question pertains to the fact that there will still be steady communications with Earth even once the ships reach their destinations. Does this difference in language present an unnecessary problem, or would the fact that the language was also used on Earth allow it to become something of an "American English: England English" relationship?
I know there are several posts with similar ideas but I think my question is a little more direct and focused.
Note: I did make the alphabet for it and it looks pretty neat when written out. For the most part it is very simple and easy to learn.
Edit: during this era, there is kind of a cultural reneisance going on. Some of the old standard systems have already been updated or changed. There may have even been push to create a new universal language and writing system. This is just to clarify that the lone creator here is not necessarily crazy or power craving, he is just someone who wants to make things easier for everyone.... Somewhat like a future Elon Musk.
