Yeah, totally doable. In Romanian we have a few extra letters but in apps that don't have support for them people just use digraphs: ș is sh, ț is tz (same sounds as I'm English for those digraphs). There's 2 vowels for which unfortunately there's no "standard" digraph, but even those should be doable, something like ă being aw and î being iw (we'd abolish the duplicate letter â, it's a waste of space, anyway, IMO).
Seems like a decent approach for the English alphabet improvements.
