Even and odd- bullpen solution?

There will be shortened time to get ready for the season.  Starters will be held back awhile as far as how many pitches/deep they go to avoid injuries.  For relievers, I think you limit innings but also avoid back to back days for awhile.  With the possibility that Kimbrell is not traded before the start of the season and he seems to be more effective closing, could he and Liam split closing duties for maybe a month while arms regain strength?  Say  Liam gets odds and Kimbrell even days.  You might have to adjust if there are blowouts but perhaps neither going more than 2-3 days without pitching.  There were times last year where I think Liam was over worked and this would prevent over work/injury risk while it exists.  If Kimbrell is pitching better in a closer role(part time) then you would maximize his trade value.  You could do similar things with the others in the pen at the start of the season for injury prevention.  Just thinking ..........
