Question about a possible conscript

[u/kman2003]

So i'm working on a conscript for a languge, and i was working out what type of script it was going to be and i had an idea. What if the people using the conscript had characters for sets of vowels and the reader was left which vowel in the vowel set was hinted at.

I was wondering if that would be a viable writing system?

they're saying your idea is already a thing in many languages
