SO this is the absolute stupidest idea in the world but Peter got technopathy as his Confluence power so there is some potential for something like, idk, if Bucky's arm breaks or goes haywire or something Peter might be able to fix it. Or...accidentally mess it up before fixing it! It's 4am and I'm spitballing.

Peter's met Bucky before (a little) but doesn't really know him or anything, but a forced team up in the future could be pretty funny as well.
