leave the diodes in and don't use them, bring out the power on leads
from the other side of the diodes for AC. the rectified power can then
be used for reedback regulation of the AC. did this years ago for
a ~1kw tube TX worked very well. it was cheaper than buying a
HV alternator (120/230v).

the auto system if well maintained can do just fine power wise.
resonable power is around 3-500W at the high side.
