For wheels, if you are going to mess around with rear dropout spacing, non-standard cassettes, off-center/asymmetric rims, etc then you may find yourself building a custom rear wheel (and potentially a matching front).
Or finding a wheelset that can be modified to your needs depending on how you choose to modify them.
Of course, by respacing the rearend, you can choose any wheelset made in the last 20+ years, again, depending on whether you choose a rear cassette 11x34 (10s compatible), or something smaller.
