We kind of have to use the standard part for this, and the standard part is not, uh, great. This is a possible problem with standards. There is a lovely Switchcraft miniature XLR which would be ideal for this, and apart from the dreadful expense, everyone apart from you would probably complain that their power leads would not fit it.
Since it bothers you, and you can solder, you maybe should probably do as you say, and hard-wire it.
