It'll work perfectly fine on any smaller "large" cogs.
You may find you'll have to turn the RDER barrel adjuster a little bit when swapping wheel sets.
just keep track of how much and it's simple.
You will want to check your low limit setting when you swap wheels so that you do not risk putting the derailleur into the spokes. You are likely to need to make minor adjustments when swapping parts, even like for like, due to manufacturing and assemble tolerances. You may also need to touch up the "B" screw adjustment for best shifting performance. Only minor adjustments should be needed but they will probably be needed to some extent.
