Alistair, once Britain's departure from the EU is final, I, and perhaps Thal, will vote for your accession to Commissioner of the EU. 
I wouldn't waste your time or your vote, for several reasons (although it's good to see someone else contributing to this thread!).
For one thing, I would not want, nor have I the experience or qualifications for, such a post.
For another, I already have quite enough to do, very little of which is affected by the lockdown.
For another, even were that not the case, I would not wish to occupy such a position without UK as an EU member state.
Lastly, the "finality" of UK's departure from EU remains what the egregious Donald Rumsfeld might have called an "unknown unknown"; until negotiations can continue between UK and EU, no further progress (or rather regress) can be made and details of their resumption are uncertain.
Arguments such as Thal's about the last of these simply do not hold water, since "the people" - i.e. the UK electorate - were not asked for their views on the many issues to be negotiated and, as with any other contract (especially one as complex and long-standing as that of UK's EU membership), it cannot simply be declared null and void without the many tens of thousands of hours of negotiation which have to date yielded little material success.
Incidentally, although I cannot and would not presume to speak for any other Remain supporter, I have personally managed to find ways around problems arising from UK's cessation of EU membership should it ever happen, so will be "business as usual" for me.
Best,
Alistair
