I did a different approach, and looked at Steamer WAR projections for the 4th OF listed on good teams:
TEX, Langford - 1.3
NYY, Grisham - 1.1
NYM, Marte - 1.1
LAD, Taylor - 0.9
HOU, Meyers - 1.0
CHC, PCA - 1.1
ATL, Kelenic - 1.0
ARI, Gurriel Jr - 1.1
Top comparables for KK as a 4th OF would be Grisham and PCA.
In any event, KK's 1.2 WAR projection fits within the above group.
