Some people prefer to keep their equipment "stock" or at least
functionally stock.  The SB-200 was never designed for 1500W
output on CW - it was designed to operate at 1 KW DC input (ca.
700 W CW or 1500 W PEP SSB output).

Pushing the SB-220 to 1500 W CW output (or worse, running RTTY
on the high taps) is a quick way to fry something.  Even the
toroidal transformer you recommend is only rated for 800 W!

73,
