Installing big contrib node on a 256M old Pi

I want to install node-red-contrib-tts-ultimate on an old Pi B (256M RAM total) and its failing/timing out

I think this is due to memory constraint

I had an idea to install it on a PiZero (same processor but 512M Ram) and then try copying it across to see it that gets around the issue

But as well as its node-modules folder - I assume I'm going to have to manually edit some package files as well

Is this even viable?
