As Bill has explained, the WSJT-X Rx bandwidth is currently limited to 5000 Hz. But I agree that larger FT8 sub-bands (or multiple sub-bands on a given HF band) are really what is required to relieve congestion.
On 6M at least, our use of spectrum for WSJT modes is quite wasteful. There's no good reason why dial frequencies of 50.310, .313, and .316 could not be used, providing 9 kHz of total bandwidth, but tying up only 9 kHz.
Better yet, if the FT8 watering hole would have been established 50 kHz lower in the band, those of us using a K3, K3S, or KX3 with P3 or PX3 spectrum display, which has a max display width of 200 kHz, could monitor CW and SSB while working FT8. I was able to do that in the JT65 days, switching between the modes to work three SA stations in two countries and 3 grids during a TE opening.
