It doesn't seem to fit the general templates of English sentences I know. Is this an incomplete sentence? Or is it a shortening of an older phrase now no longer used? What are the subject and the object here?
Would is "archaic" which means old and no longer used. People use "I wish" in place of "(I) would".
I wish I were more handsome. I would I were more handsome. (archaic)
It is well explained in Merriam-Webster. Please click here.
a archaic: wished, desired
b archaic: wish for : want
c (1): strongly desire : wish —often used without a subject and with that in a past or conditional construction
(2)—used in auxiliary function with rather or sooner to express preference
