The Scottish system already does this. Students apply between October and January. They may already have some Highers in the bag from S5, state what extra Highers they are studying in S6. They then get offers based on this, either unconditional (if they already have enough) or conditional based on results day in the August. If they don’t get the final results, they don’t meet the conditions, they don’t get in. So they have already done the ucas bit, whittled down from 5 to 2 offers waaaay before results day hits.
Scottish unis start a year before English, Welsh and NI ones though. If we moved to the more radical of the proposals (apply after results), we'd have to move to a start date of January. Making the age gap between Scottish starters and English even wider. Not to mention the problem of a million 18 year olds claiming universal credit for the four months after they got their A levels and before uni started.
Now if Mr Gove hadn't decoupled AS levels from A levels we could have had a system much closer to the Scottish system, with no need for predicted A level grades because half the course would have been completed and graded.
