It might take some work, but would this engine work?

This is imho not true. All our targets should have enough processing power
to run realtime TTS. A plain Amiga 500 (7MHz MC68000, 512KB of RAM) was able
to do it in the 80s, with a narrator.device of ~64KB and a
translator.library of ~13KB.
(Note: These are enhanced versions - the original AmigaOS 1.3 versions were
probably still smaller)

The biggest hurdle on archos was the inability to play PCM samples - but
that's possible now thanks to the PCM codec.

The real challenging task now would be to actually write a compact,
efficient, opensource TTS engine, preferably supporting more than one
