Nah. Institute story was actually the only interesting one. You should do their storyline. Gives at least some light why is their reasoning. That story wasnt just black or white.
Tbh, what could you do after ending F4 storyline? More settlements? :P Dunno. I was hyped for F4 for so many years and got only totally dissapointed.
No thanks. The backstory on the Institute included the fact they were deliberately making supermutants, organised an assassination attack at the peace talks, are routinely kidnapping people and replacing them, their concept of "Mankind Redefined" included pseudohuman "children"..for all their flaws, at least the Minutemen wanted to at least help rebuild.

Preston may be annoying, but his heart is in the right place.

I LOVED building settlements..also took perverse joy in sending Marcie Long to live with the ghouls. I didnt like Old World Blues, Lonesome Road was my only real favourite DLC in New Vegas. I felt akin to Ulysses..loved his foresight of the future.

Far Harbour was a load of fun. Oh and the radio? There are loads of mods with some VERY cool stations, one of them was early jazz. You havent lived until you roam the wasteland to the voices of Dizzy G, Satchmo, Duke Ellington and of course, now and forever, the great and only Count Basie. The addon also had big band tracks, ahh yes, those were the days.

( P.S Salty..at the end of that Mel Brooks movie? Blazing Saddles? The guy on the piano was Count Basie himself, the man had the gift and he had STYLE )
