I came back to this old thread to find many more responses than I remembered. So for the sake of an update, let me sort-of describe what I've done to help improve pistol skill while also not allowing other skills to deteriorate
The road that I've taken since originally posing this question has been to take the advice given and begin shooting USPSA (and IDPA when no USPSA is around). I've shot probably an average of 2.5 pistol matches a month, opposed to the 1.5 three gun matches I averaged prior. I didn't shoot any of the 3 Gun Majors this summer (as hard as that was haha) so it's hard to gauge how my performance has increased (in that realm) based on where I started. I do certainly feel far more confident on the gun than before, especially with taking certain tighter shots that otherwise might have intimidated me in the past...I "expect" to score Alpha's now. While I still can't seem to beat a Mid-A classifier time on the majority of classifiers (others which are more standard drills which I have practiced I'm able to hit M based on the calculators) my overall match scores have increased by 10-15% on average from when I stared this training regiment.
I haven't shot a whole lot of rifle or shotgun in this time period, but every so often work dry fire and reloads to be sure to keep the skill present. I know when it comes time I won't be able to pick up the gun and be as fast as before, but in 2-5 range sessions I'm confident I will be.
Despite what one person posted above, I argue that time is indeed finite, as is money...we need to tailor our training regiments according to our skill sets and what we have analyzed needs improvement based on match scores.
Again, thanks for the input and responses....the quest continues!
