Sending just another similar telescope that provides more same typed data (wavelength, angular resolution) is probably not worth it. Spending the same sum for different type of telescope would be better use of the money.
Hubble, Hershel and Webb were are made for different wavelengths, they are complementary.
The Extremely Large Telescope (ELT) is ready around 2027 and it will be the next revolution. 0.005 arc-seconds compared to 0.1 arc-seconds of JWST. (978 m2 vs 25.4 m2 collecting area)
