Under approval voting, it's pretty clear what's most popular with Parliament:
(1) Second vote
(2) Customs union
So, have a second vote. What should you vote on? Well, that was also answered:
"Should we (A) stay in the EU or should we (B) leave the EU and have a customs union with the EU instead"
Of course they will not do anything as sensible as to have a vote on that
A second vote might sound sensible from an academic perspective but for well rehearsed reasons, would only serve to prolong economic uncertainty and further undermine social unity.
It would also be somewhat perverse to have a referendum including an option (Remain/Revocation of Article 50) that has already been discounted by both the electorate (in the 2016 referendum) and parliament (multiple times in recent weeks). Especially given you wish to exclude from such a vote the option that seems to have growing and very possibly soon majority public support:
Fortunately the UK has a perfectly sensible and very well established system for deciding between multiple possible political courses. That system is to run a general election under first past the post. I suspect we'll have one soon, where the voters will be given an unambiguous choice between all of: referendum or straight revocation of article 50 (Lib Dems, TIG, SNP), exit with a customs union (Labour), exit broadly according to the Withdrawal Agreement (Conservative) and exit on WTO terms (Farage Party, UKIP, possibly Conservative depending on who the new leader is).
