I used to do this, but I never found a good solution to scratch all the itches that come up when you go down that road. For instance you want to keep a variety of config in sync between all accounts -- except for the bits you don't. You want to be able to share some files between the accounts, but not others due to security concerns. You want to be able to access things like your password manager or mailbox, which again you may not want to share between accounts for security reasons. Sure, there are solutions to each of those problems, but in the end I found it required more discipline and effort than I was willing to put in, for what basically amounts to a small amount of additional security. I'd be happy to hear how you deal with those issues, however!
