Can Catholics receive a canonically valid marriage after civil elopement?

Accepted answer
No, as this is considered adultery. But it's not a barrier to Catholic marriage later.
Civil marriage (as in by administrative officer) is not considered valid by C.C. I know this for a fact(s):
Information given when attending pre-marital course as required by CC for marriage (with a host of other, very useful news).
I know of at least two couples where this exact scenario happened: first, the civil union, then after a 6-8 months church marriage. Not sure of the penance, though.
