Silly name combos

The 19-year-old poster below amused me, because I STILL make up lists of baby names, though not as often as I did 20 years ago, maybe because I despair of ever having kids at this point. The thing is, I have very definite likes and dislikes in names and I'd really hate to have a kid of mine bearing a name I didn't like, even as a middle name. I tend to associate names I don't like with certain people I knew who had those names and with whom I had a bad experience. Anyway, I know it's often frowned upon to change the names of older kids, but what if the name combination is just ridiculous and would make the kid a laughingstock? Something like "Hiroshi Rabinowitz" or "Mstislav Hartington" I have a very English surname and have considered mainly adopting from Russia, so this question has come up. I know some people keep the original name while others Americanize it and still others change it completely, so you'll have a little girl of Cossack ancestry bearing a silly American yuppie name like "Bree" or "Kelsey." But if the foreign name is just too foreign or hard to pronounce what is usually done--do you find a name that begins with the same letter or that has some of the same sounds in it? One of my idiosyncracies is I would want to give my kids long strings of names, like Hispanic Catholics or royalty do. ;-) This is not so much out of pretention, though, as it is that there are quite a few names I really like and that are deeply meaningful for me, and I'd hate to be limited to two or four or six. And yes, many names are meaningful for me---this isn't just a case of picking something out of a baby book that sounds kinda cool. (Off topic, does it seem that it takes a really long time for stuff to load on this site? I have DSL, but the site is really slow.)
