You can recast a character and nobody bats an eye, but change the angle on the Enterprise's nacelle pylons...Doesn't really matter if Boimler didn't bat an eye when he stepped onto the Enterprise. Neither did Sisko, Jadzia, O'Brien and Bashir when they stepped onto the Enterprise. And Scotty pulled up Kirk's Enterprise on the holodeck, which was also Pike Enterprise in 2254, instead of Pike's late 2250s Enterprise.
