Yes I think so. Andrelton Simmons has a career .380 SLG.
Hitting HRs didn't win in the 80s because teams weren't trying to win that way. Modern FOs realize you're better off taking a walk and waiting for a bomb than giving away outs and trying to manufacture runs.
Of course market values also influence how MLB teams put together their rosters. If small ball skills became undervalued, I'm sure eventually you'd see a shift in that direction, at least somewhat. But as long as there are only 3 outs and 4 bases, avoiding outs will always be more valuable than taking an extra base.
My opinion is that the open air stadium teams will still have trouble winning WS titles if they favor the long ball over pitching and defense. The HRs will win a lot of RS games, but look at how many warning track fly balls there were in this past post-season (that probably would have been 5 - 10 rows up during the summer.
I get it's all relative if every team looks alike; but, the Astros never won their first title until they spent the money on Verlander and then almost repeated when adding Cole to go with him.
