i think that the comparison between the names and the modernized clothing is not fair. though both mens and women’s clothing has changed since way back when, we have for the most part (short skirts and shaitels, esp long ones, notwithstanding) retained our mesorah of tznius. this was always the accepted derech — is there any mekor for saying otherwise? even the chassidish levush dates back only to pre-war europe, when they made a stand and refused to adopt the short jackets of the time.
jewish names are kadosh. i agree with the OP – both my sons have somewhat uncommon (not strange though) torah names that are hard to pronounce – if at some point they are forced to adopt some kind of nickname to survive college/business/etc that’s their choice, but i wouldn’t put the name on them.
