No - a 50-400 (better OSS and a bit better IQ than the Tamron, plus full high speed AF) would be the best idea.
It seems like the best idea is a tele-zoom that isn't a slow slide into comparative optical mediocrity in the longest third of its range. Lenses like the original 100-400GM and Canon's 100-500L are at their objective best at 100 and every mm zoomed robs a little resolution and adds poorer correction for common problems. They've got good object definition throughout their ranges, but they're both light on the details at their longer settings. Even Sony's pricier 100-400/4.5 GM doesn't entirely escape this.
