If China sees Russia take part or all of Ukraine, why wouldn't they?
It's clear if you pay attention, that China's putting inordinate efforts into other places. Africa is one example. (Probably the principal example.) So they clearly have ambitions that lay outside of Asia.
No one fakes moves like that at that scale. They're serious about what they're doing.
That being said, even if they would. Under that assumption, I find the idea to further provoke them to doing that morally repulsive. It's an egomaniacal move that disregards Taiwanese people.
They won't be affected personally (unless the country rebels against them) so they can be fine to tank the economy if it gets them closer to some other goal (such as megalomaniac world domination).
"Provoke" means doing something with the intention to trigger an emotional or other reaction. That's not what Taiwan is doing.
