Yes. In the last millennium I installed a Chris King headset on my first Superior so I could install a “normal” fork and handlebar stem. (22.2mm inside diameter instead of the Schwinn 0.833” ID.) That bike eventually got cantilever brakes and a first generation Shimano Deore cranks.
Nothing I do is normal.
