Can subject–auxiliary inversion in conditionals be used with non-auxiliary (arbitrary) verbs?

Question

Can I say something like

Come you there, I'll get you.

?

Or should I only say something like

Should you come there, I'll get you.

?

I understand that it looks like I must use an auxiliary verb in a subject-auxiliary inversion kind of by definition :) But I'm just not sure if I absolutely need it.

Answer 1

You don’t say:

• Come *you there, I’ll get you.

Because the you is wrong.

For that matter, so is there since the locative deictic that pairs with come is here not there; there pairs with go.

You instead say:

• Come here and I’ll get you.
• Go there and I’ll get you.

Which means:

• I’ll get you if you come here.
• I’ll get you if you go there.
