It won't unfortunately, because levelling is very important to PvP population - we've always assumed PvP was only as high as it was because bungie funneled players in there for levelling & things like catalysts & quests & when lightfall had no levelling, as expected PvP & gambit numbers both fell through the floor with a 65-70% dropoff almost instantly. Minimum daily numbers would be 300km this was all time lows, then in lightfall we hit 120k, then we went as low as 65k, it's now around 90k but never recovered & won't. Renegades has no levelling so won't push people to crucible & there's almost nothing else they can do.

Unfortunately playing 100+ matches of control will get boring. Trials is notorious to casuals for being sweaty confetti. Bungie decided to add cutting edge, which restricts gear and build usage. Got a weapon type you like but not in the right element? Unlucky son. Pvp didnt get any new maps in 2 years..I remember SRL populated the crucible a bit more back in the day because it was a fun casual mode
