Some "theoretical speculation" :
With regard to swing mechanics,I would say first of all,is a power swing required or does the situation demand a placement swing ?
I like Epstein's overall approach myself for power hitting and for how to shorten up (still hit hard/don't change essence of swing mechanics) for more plate coverage/less power as for 2 strikes.
This is a little different from the options for the hitting outside situation.In any case you need a plan.
Hit and run may mean you have to poke the ball to right (assume righty hitter).In this case an "inside out" keep hands ahead of the bathead placement swing may be indicated.These are very different mechanics from power or shortened up/"2 strike" hitting.
If you want to hit for power,but improve the odds of hitting ball to oppo field or hitting a fly,then above all you have to "know yourself" and what the results are likely to be depending on what pitch you look for and how/where you are likely to hit it.Anticipate a pitch that you can do this with/"get a good pitch to hit".If you just want to be able to hit outside when you are looking there and don't care where it goes,that is a more basic mechanical adjustment/learning issue.
In general,the type of power "rotational" mechanics optimized for quickness (not a placement swing,not optimizing for max batspeed) is much like SBK describes.The body separates/coils some before committing to the swing.For outside.There is longer swing radius and probably more separation/coil before this triggering/commitment/point of no return happens.This means there is more "extension" of the bathead (while swing radius is longer than for inside,it still needs to be "SET" before the bathead "launches") than for inside.This more extended bathead means the body has to work more to accelerate a higher "load"/further out bathead.This means the hips turn open less to contact and more separation is created before the uncoiling that accelerates the bathead rapidly begins.
"Seeing" this is very subjective when trying to use the naked eye even supported by slowmo video.Motionanalysis (computer aided video using reflective markers on hip,shoulder,lead hand and bathead as per skilltechnologies.com,for example) may be of some help aggregating data here,although even this has lots of room for error/assumptions,etc.)Here is a link to a description of their data which supports less hip turn/more separation for outside.Hypothesizing the relation of the longer swing radius as an essential part of this comes from Mankin's theory at batspeed.com.See what you think.
http://www.batspeed.com/messageboard/10533.htmlIf you swung according to this quick rotational power theory,however,you might hit the outside ball more to power ally or up the middle WITHOUT degrading mechanics by "hitting around the ball",but that is another discussion which differs from Epstein's "theory" ("pinball"/let it get deep oversimplification).
Know yourself.Have a plan.If your skillset means your options are limited,focus practice on giving yourself more options/tools and knowing yourself better.
