No springs - apply to summers or springs again?

Hi guys, 1st year at a UK high semi-target for context. Got 4 interviews for springs but didn't manage to get any of them. I am thinking of applying for summers later this year, but maybe combining it with some spring week applications. For example, Lazard's summer cohort seems to be mostly filled w spring converts; if this is the case, I might as well apply for the spring again, right? Are there any other banks where the summer cohort is filled w spring converts? I'd be very grateful for any insights.
