As long as you keep in mind that there are external factors, you could probably compare his runs per plate appearance to his on base percentage. Or his runs to his times on base. With a large enough sample size it might be meaningful.
Random examples (I'll try to use extremes...a few dirt slow guys, a few fast guys, varying OBP skill):
Ja Giambi - (851 R - 281 HR)/(1413 H - 281 HR + 871 BB) = .284 R/TOB .147 R/PA
V Coleman - .438 .142
R Henderson - .404 .172
T Cobb - .400 .172
T Raines - .372 .152
B Ruth - .346 .205
B Bonds - .316 .179
T Williams - .307 .184
F Thomas - .278 .154
M Vaughn - .264 .134
E Lombardi - .202 .095
Vaguely correlates to a player's speed, altho I'd have to question Babe Ruth ranking Higher than Barry Bonds. It could also just correlate to one's typical position in the batting order...I can't think of anyone offhand who led off most of his career with no speed or hit low in the order with wheels.
If either of these stats meaningfully correlate to a skill, I'd expect them to be fairly consistent over a player's career regardless of team/lineup spot, with a decline for age.
