I thought the exact same thing when I got my 100T/410Neo rig five years ago, but other than gassing for the look of 2 410Neo's stacked or side-by-side, I've had absolutely no reason to do it. The single 410 with the 100T has more than handled any gig we've had, and we've played some really big outdoor festival stages during that time.My thought process would be to get a 100T with a 4x10 for normal gigs with the option to buy a 2nd 4x10 down the road. If I got it over the Super Bassman, which is undecided.
